Updates:

• 1/1/06:

  Roadmaster has stopped making BrakePro and replaced it with a revised system that it calls Even Brake. A DRAFT review of the Even Brake System has been added. Like the other reviews, if you have a correction or addition, please post it in this thread or send me a PM

  An update to the M&G review - New optional alert system, new warranty.

  
  
• 8/07/06:

  Added comments about BrakeBuddy's new system 'Vantage.'

Choosing an auxiliary brake system for our toads seems to be almost as challenging as choosing our RV’s. I hope to write a post that provides useful information about the different braking systems that are available. I do not intend for this thread to advocate for or against any system – I want it to just provide information.

To be useful, the information needs to be accurate. I have personal information about only two systems. All of the other information comes from the Internet. I would like for those who use a particular system to correct errors or provide additional information so that an accurate, final post can be made to serve the members of the forum. Again, please, I do not want this thread to be an advocating thread.

I will attempt to classify the braking systems based on the mechanism or process that triggers activation of the toad’s brakes. At present, I think this can be done with one of the following three categories.

• Surge
  A slide receiver is used for the tow bar. As the motor home slows down, the toad pushes on the slide receiver.
  
  
• Deceleration
  The toad (or motor home) slows down faster than some predetermined value. A mercury switch, pendulum system, or accelerometers are used to detect the deceleration. Some of these systems require that the motor home’s brake pedal to be depressed also.
  
  
• Pressure applied to motor home’s brake.
  

Since different manufactures use different meanings for some of the important terminology, here are the definitions that I will use in this report.

Proportional: The toad’s brakes are applied in proportion to the pressure on the coach’s brake pedal.

Invasive: Installation of the system requires insertion of a connector in the toad’s (or coach’s) vacuum line, hydraulic line, or air lines (coaches with air brakes.) Invasive will not be used to describe mounting of vacuum pumps, air cylinders or cables.

Permanent installation: One does not have to remove devices from the toad before driving the toad. Although this does not mean that one cannot move the system to another toad; it does imply more than a casual amount of effort. Conversely, a non-permanent installation implies that part of the system must be removed prior to driving the toad. Non-permanent also implies that the system can be easily moved to another toad.

(See BrakeBuddy for a similar system)
Deceleration system. Accelerometers are used to detect a decrease in forward momentum. When triggered, an air cylinder extends an arm to apply pressure to the toad’s brake pedal.

Monitoring. Application of the toad’s brakes is signaled (radio) to the coach. The signal indicates the toad’s brake light switch has been activated. The transmitter is wired to the cold side of the brake light switch. The transmitter setup is permanent, in the sense that it is not removed to drive the toad. The transmitter requires a 12-volt DC connector. Since the base unit requires a 12-volt DC connector, the combined systems require two.

Adjustments to the system from within the coach: None

Adjustments to the system from within the toad: The sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. The amount of pressure applied to the toad’s brake pedal can be adjusted.

The toad’s brakes cannot be applied independently from the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes.

Is not proportional

Is not an invasive system.

System uses the toad’s electrical system. The unit is plugged into the 12-volt DC adapter. Note: The alert system also requires a 12-volt connector.

Installation is not permanent. The unit must be removed before the toad can be driven. Although the installation and removal is a simple process, the unit must be stored somewhere while the toad is being driven.

BrakeBuddy
(See Apollo for a similar system)

BrakeBuddy has come out with an updated version which they call 'Vantage.' Since I'm on the road now, I will have to wait until I return home later in August to fully investigate the new system. Here is a link to BrakeBuddy's Vantage page.

At first glance, here is a summary of changes: 1) The abiltity to change the Sensitivity settings "on-the-fly" from the coach. 2) A digital pressure guage that allows for more precise pressure settings. 3) Automatic setup feature.

The flyer mentioned above appears to misuse the work 'sensitvity' in the lower righ-hand corner. There it describe it as adjusting the braking force. 'Sensitivity' is used to adjust how quickly the system will activate. I believ member GotSalt has the new system. Give him a PM if you have a question.

I will make a full report after I return home and can contact the company.

BrakeMaster 9000 & 9100 Series by RoadMaster
Pressure applied to the coach’s brake pedal causes a proportional amount of pressure to be applied to the toad’s brakes. Air pressure is transmitted from the coach to an air cylinder that is non-permanently mounted in front of the driver’s seat. The air pressure can come from the coach’s airbrake system or, in the case the coach has a hydraulic brakes, from a compressor mounted in the coach. (See below) Note: The toad must have power brakes to use the standard BrakeMaster systems. An optional pressure regulator can be purchased to adapt a non-power brake toad.

Monitoring: Application of the toad’s brakes is signaled (wire umbilical cord) to the coach. The signal indicates that the toad’s brake light switch has been activated.

Adjustments to the system from within the coach: None

Adjustments to the system form within the toad: None

The toad’s brakes cannot be applied independent of the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes.

Is proportional

Is invasive: 9000 Series: A hydraulic line must be run from the proportioning valve and tap into the coach’s hydraulic system at one of several possible locations.
9100 Series: For coaches with air brakes, a port on a relay valve near the rear axle is used to tap into the coach’s air brakes. For coaches with air-over-hydraulic systems, a port in the air booster near the coach’s front axle is used to tap into the air system.

Uses the toad’s electrical system. (Looking at the wiring diagrams, it appears that the toad’s battery could receive a charge from the motor home. That is not listed as a feature, Can anyone shed a light on this?)

Is not permanent in the sense defined for this review. An air cylinder must be attached between a mounting post and the toad’s brake pedal. The mounting post is affixed to a circular base plate that is bolted to the floor through hole drilled through the floor panel immediately in front of the driver’s seat when in its furthest back position. Seat adapter brackets are available for some vehicles. The seat adapter replaces the floor base plate and is secured by the seat channel bolts. In addition, the 9000 series requires the installation of an air compressor on the coach in “clean, dry place.” A storage bay is recommended. Also, a proportioning valve must be mounted on the chassis.

Has a breakaway system that requires the mounting of an air tank (usually under the hood). The air tank should be drained regularly to prevent moisture buildup.

BrakePro by Roadmaster

Roadmaster has stopped manufacturing BrakePro is now producing a similar system, Even Brake. A review of the Even Brake system can be found alphabetically below. Since BrakePro can still be purchased at discount prices, this review will remain for awhile.

Deceleration system. Accelerometer(s) are used to detect a decrease in forward momentum. When activated, an air cylinder pushes forward an arm to apply pressure to the toad’s brakes. Based on rate of deceleration, software determines how much pressure, up to a user determined maximum, is used to apply the brakes.

Monitoring. Application of the toad’s brakes is signaled (radio) to the coach. The signal is base on whether or not the cylinder’s arm is extended.

Adjustments to the system from within the coach: None

Adjustments to the system from within the toad: The sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. The amount of pressure applied to the toad’s brake pedal can be adjusted.

The toad’s brakes cannot be applied independently from the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes.

Is proportional: This is somewhat different from that which is usually described as proportional. The proportionality is based on the rate of deceleration as opposed to the amount of pressure on the coach’s brake pedal. In addition, the user determines a threshold, which must be met before the toad’s brakes are applied. And, finally, the user determines the maximum amount of pressure.

Is not an invasive system.

System uses the toad’s electrical system. Note: A 20-amp DC connector is required. Not all cars provide such a connector; many have only 15-amp connectors. Roadmaster sells a battery-direct 20-amp DC connector that is easy to install.

Installation is not permanent. The unit must be removed before the toad can be driven. Although the installation and removal is a simple process, the unit must be stored somewhere while the toad is being driven.

Based on rate of deceleration, software determines how much pressure, up to a user-determined maximum, is used to apply the brakes.

Monitoring. Application of the toad’s brakes is signaled (radio) to the coach. The signal indicates that the toad’s brake light switch has been activated. Even Brake also monitors the toad’s battery. (See below.) The transmitter setup is permanent, in the sense that it is not removed to drive the toad.

Adjustments to the system from within the coach: None

Adjustments to the system from within the toad: The sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. The amount of pressure applied to the toad’s brake pedal can be adjusted.

The toad’s brakes cannot be applied independently from the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes.

Is proportional: This is somewhat different from that which is usually described as proportional. The proportionality is based on the rate of deceleration as opposed to the amount of pressure on the coach’s brake pedal. In addition, the user determines a threshold, which must be met before the toad’s brakes are applied. And, finally, the user determines the maximum amount of pressure. Maximum pressure is use for emergency stops.

Is not an invasive system.

System uses the toad’s electrical system. The Even Brake monitors the toad’s battery and will transmit a signal to a monitor in the motorhome to indicate a low battery condition. If the battery’s voltage drops “too low,” the Even Brake cuts power to itself and retains only emergency braking function.

Installation is not permanent. The unit must be removed before the toad can be driven. Although the installation and removal is a simple process, the unit must be stored somewhere while the toad is being driven.

M & G Tow Brake

Update 2/22/06: Now has an optional wireless alert system and a new warranty.

Pressure applied to the coach’s brake pedal causes a proportional amount of pressure to be applied to the toad’s brakes. Air pressure is transmitted from the coach to an air-over-hydraulic cylinder inserted between the toad’s vacuum booster and master cylinder. The air pressure can come from the coach’s airbrake system or, in the event that the coach has a hydraulic brake system, from a compressor attached to the coach. (I’ll describe this process later.) Note: The toad must have power brakes and some vehicles with a certain type of antilock brakes cannot be fitted with this system. Contact the company to determine if your toad can be fitted.

Monitoring: An optional, wireless alert system based on Blue Ox's alert system is available. The alert uses a pressure switch attached to the the M&G air cylindar to detect when the toad's brakes are applied. It transmit a signal to a receiver in the coach.

Adjustments to the system from within the coach: None

Adjustments to the system from within the toad: None

The toad’s brakes cannot be applied independent of the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes. Note: This is rather meaningless. The M & G tow brake is its own power brakes. No pressure is applied to the toad’s brake pedal or brake arm.

Is proportional

Is invasive. A T-connector is inserted into the coach’s existing air system at a rear relay valve (for RV’s with airbrakes) or a T-connector is inserted into the coach’s hydraulic lines (for RV’s with hydraulic brakes). In addition, an air cylinder is inserted between the toad’s vacuum booster and master cylinder.

Doesn’t use toad’s electrical system.

Permanent Installation (as described above). In addition, for coaches with hydraulic brakes, a tray consisting of an air compressor, air storage tank, pressure switch, and proportioning valve is secured to the coach’s frame or cross member. The coach’s hydraulic system is connected to the proportioning valve by inserting a T-connector between the flexible brake line and the steel line. An air hose is routed from the proportioning valve to the rear of the coach. For RV’s with airbrakes, an air hose is routed from a rear relay valve to the rear of the coach.

Has a breakaway system which is purchased and installed separately. The breakaway system requires the installation of an air tank, diverter valve and trip switch on the toad. The air tank is pressurized at the start of each day’s drive by fully applying the coach’s brakes for one minute.

Warranty: M&G Engineering warrants its product to be free from defective material and workmanship for a LIFETIME of service to the original purchaser on the M&G brake cylinder only. The hydraulic control valve carries a three year warranty. Any electrical components (compressor, switch, valve, etc.) carry a one year warranty.

ReadyBrake
Surge system. A hydraulic system on the slide receiver uses a cable to pull on the arm of the toad’s brake pedal. A factory set threshold is used to prevent application of the toad’s brakes on minor pressure against the slide form the toad.

Monitoring. Application of toad’s brakes is signaled to the coach. There are two options to choose from. Their older system uses a wire from the toad to the RV; their newer version is wireless. The alert systems are wired to the cold side of the toad's brake light switch.

Adjustments to the system from within the coach: None.

Adjustments to the system from within the toad: None

The toad’s brakes cannot be applied independently from the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of its brakes.

Is proportional.

Is not an invasive system, but requires the installation of a pulley on the toad’s firewall.

System does not use the toad’s electrical system.

SMI
SMI makes four supplementary brake systems: SilentPartner, FourWire, PlugAndPlay, and Stay-IN-Play. Describing the systems is more complex than that because a Stay-IN-Play variation can be applied to the SilentPartner and FourWire systems. I will try to get the pertinent points across in the review.

Deceleration system (combined with coach brakes). A mercury switch, located in the coach (SilentPartner and FourWire) or in the toad (PlugAndPlay and Stay-IN-Play), is used to detect a decrease in forward momentum. (Note: the SilentPartner may use accelerometers instead of a mercury switch.) In addition to a decrease in forward momentum, the coach’s brake lights must be on (from pressing the coach’s brake pedal). When activated, a vacuum operated arm applies pressure to the brake pedal arm. The vacuum system also is applied to the toad’s power (vacuum) assist unit. The Stay-IN-Play system uses a vacuum cylinder ‘permanently’ attached to the brake arm. It is this part of the system that can be used by the SilentPartner and FourWire systems and eliminates the need to store the vacuum arm before driving the toad.

Monitoring. Application of toad’s brakes is signaled (radio – except FourWire system which uses wires between coach and toad) to the coach. The signal indicates that toad's brake light switch has been activated.

Adjustments to the system from within the coach: With the SilentPartner and FourWire systems, the sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. The amount of braking cannot be adjusted in the coach. With the SilentPartner, you can select between ‘Latched’ and ‘Real-Time’ modes. The toad’s brakes are applied the same in both modes. In ‘Latched’ mode, the toad’s brakes stay on "as long as the coach's brakes are on, regardless of the inertia." When in ‘Real-Time’ mode, the toad’s brakes are released when the forward momentum is sufficiently reduced.

Adjustments to the system from within the toad: With the PlugAndPlay system, the sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. The amount of braking can be adjusted for all four units.

The toad’s brakes can be applied independent of the coach’s brakes. (SilentPartner and FourWire systems only)

All systems use the toad’s power (vacuum) assisted brakes.

Is not proportional. Note 1: A misconception exists that if a system uses the toad’s vacuum system, then it must be proportional. That is not necessarily true. With the SMI systems, a fixed amount of vacuum is used; the amount of braking is constant. Note 2: With the Stay-IN-Play variation, the brakes in the towed vehicle are applied progressively harder in a panic stop. The longer you are in the panic, the harder the towed vehicle brakes are applied

All four systems are invasive. A T-connector and check valve are inserted into the toad’s vacuum system

Uses the toad’s electrical system.

The connection to the toad’s vacuum system is permanently installed. Without the Stay-IN-Play variation, part of the systems must be removed and stored before driving the toad.

US Gear Unified Tow Brake
Deceleration system (combined with coach brakes). Actually, I’m not sure whether it is the motor home’s brake light switch or accelerometers detecting a decrease in forward momentum that triggers the application of the toad’s brakes. In either event, both are involved. When triggered, accelerometers and software in the coach are used to determine how much pressure should be applied to the toad’s brakes. The actual application of the toad’s brakes is affected with a push/pull cable driven by an electric solenoid. The system also uses a vacuum pump to enable the toad’s power (vacuum) assist system.

Monitoring. Application of the toad’s brakes is signaled (wire umbilical cord between motor home and toad) to the coach. The signal originates from a small power module in the toad.

Adjustments to the system from within the coach: The braking force of the toad’s brakes relative to that of the motor home’s brakes can be adjusted.

Adjustments to the system from within the toad: 'Tweaking' of the solenoid is done when the system is first installed.

The toad’s brakes can be applied independent of the coach’s brakes.

Uses the toad’s power (vacuum) assist system.

Is proportional. Note: The proportionality is to the deceleration rate of the coach instead of the pressure on the coach's brake pedal.

Is invasive. A T-connector and check valve are inserted into the toad’s vacuum system

Uses the toad’s electrical system. The toad's battery is charged by the coach's alternator using a line in the wire umbilical cord between the coach and the toad.

Permanent installation. A vacuum pump is mounted in the toad’s engine compartment. A T-connector and a check valve are installed in the toad’s vacuum line. A pulley is attached to the inside firewall. A solenoid is mounted inside the toad.

VIP Tow Brakes
Deceleration System (combined with coach brakes). A mercury switch, located in the coach, is used to detect a decrease in forward momentum. In addition to a decrease in forward momentum, the coach’s brake light must be on (from pressing the pedal). When activated, a high-speed electric actuator applies pressure to the toad’s brake pedal arm.

Monitoring: Application of the toad’s brakes is signaled (wire between coach and toad) to the coach.

Adjustments to the system from within the coach: The sensitivity – how quickly the coach must be stopping before the toad’s brakes are activated – can be adjusted. Automatic braking can be turned off.

Adjustments to the system from within the toad: The amount of force applied to the toad’s brake pedal arm is set with a pressure regulator on the actuator assembly.

The toad’s brakes can be applied independent of the coach’s brakes.

Does not use the toad’s power (vacuum) assist to aid in the application of brakes.

Is not proportional.

Is not invasive.

Uses the toad’s electrical system. The toad’s battery receives a trickle charge from the coach’s electrical system.

Installation is not permanent (as I have defined permanent). A bracket is mounted to the floorboard of the toad and to the brake pedal arm. The actuator is connected between these two brackets when towing. The actuator must be removed and stored from driving. The process involves removing a couple of pins. In addition, there is a one-time wiring installation. The controller in the coach and the actuator communicate through a wire – wire form front of coach to rear, a wire from the actuator to front of toad, and a jumper between them when towing.

Bill, (Hayhauler)

I've looked at the Remco system, but don't have enough info to make a report yet. I have asked the company for a brochure. As of yet, it has not arrived.

There is a break-away system that is included free. ($105 value, if you ask them.) I know that it is a cable that is attached to the RBS receiver on the coach and to the break pedal. Supposedly, if the toad breaks away, the cable will pull on the brake pedal. In talking to them on the phone, I could not get a clear image in my mind as to how this is going to work. I asked if there was a clamp that was then going to hold the cable and I got a 'yes, well no.' answer. I asked if the cable was to stay attached to the coach (and the coach continues to drag the toad down the highway). Instead of an answer, they offered to send a brochure.

I did determine that there is no alert system.

Hope this helps. If I get more info, I'll pass it along.

Tom

[Hayhauler]

Tom,
Great work!

Do you have any info on the Remco brake system. I am looking at it because it is a surge system, it is simple to connect (one line for brake fluid), and the price seems very reasonable. My concern however is I cannot find much info on their breakaway system, and their receiver has to be welded on beneath the existing receiver if you do not have a minimum of 20 inches clearance. If you have any further info it would be appreciated.

[Nicksrick]

Thank you for all of your hard work and anaalysis Tom!

One plus for US Gear's Unified Tow Brake is having a nation wide network of service installers.

VIP Tow Brakes does not have such a network of service installers in the Western United States.

What about the Appollo braking system similar from Blue Ox to Brake Buddy but is digitized and more accurate maybe? What are their advantages over BB?

Toban

[TimHayden]

I have the tow brake system - and so far have been happy with it. It does take some effort to make the initial installation - but works well. The pressure regulator is not adjustable as far as I can tell. There is a lever on the end of the linear electric motor where it attaches to the brake pedal - the lever is loaded by a spring - like a snow plow - if the motor pushes harder than the pedal needs, the pressure of the spring is overcome and the lever flexes.

The comment on the lights - there are small leds - on the M/H cab mounted control box - I have mine on the left wall. This also contains the mercury switch, the sensitivity adjustment, the on/off switch and a push button to activate the toad brakes without the M/H brakes. Green led on - power on, system OK. Red light on, brakes activated (at beginning of activation, short burst from buzzer. If cord from toad becomes unplugged (breakaway) the buzzer sounds continuously and the brakes are applied.

It takes about 2 - 3 minutes to install - putting pin in brake pedal bracket under dash is worst part.

Feel free to send a PM if you would like more info.

Fred (fcooper)

Thank you for all of the help you have provided. Your comments in the thread, private messages, and email have been very useful. I have communicated (phone and email) with Peter Schuck II, the president of SMI. I still have an email question that he hasn't responded to, but I sure am impressed that he took the time to communicate with me. He described the way they test their products, answered some basic questions, and talked about some interesting things they are planning. (I'm not allowed to say what.) I have emailed the other companies asking for input in the post. So far none of the others have responded.

One more item about the SMI stay n play. The box that remains under the drivers seat maintains the vacuum for the toad power boost system. This vacuum setting is adjustable. It appears that by changing the vacuum pump setting the braking force in the toad is changed also. Mine was adjusted slightly low, and after increasing the vacuum setting the toad seems to brake a little more.

Regarding your question about "invasive", I really was not concerned about inserting a T connection into the vacuum line. Getting into the hydraulic system is more invasive than the T fitting in the vacuum line. I'm not sure your report has space to define how invasive the installation becomes, but it might be helpful info.

Still no answer to my email question to SMI.

[Kajtek1]

The VIP constructed the chart, so their system looks good and the others bad.
Let's take "System status indicator light(s) in M/H (number)"
Do you care about having a discotheque on your dashboard? According to VIP having 3 lights is a good thing. I would say give me one red light, when something is wrong and forget the rest.
Personally for me the most important in braking is the maximum braking force and proportionality.
I would rule out all the systems, that wouldn't give me at least 50% of maximum braking force. Since this is very "unpopular" subject with the manufacturers, I suspect that only couple systems can deliver 50% of the performance.
The same goes to proportionality, what was "avoided" in VIP chart.
Go, figure.

[pulsar]

Thank you, John (justlou).

In another thread, I posted a link to the chart itself.

VIP Enterprise's Comparison Chart

I think it is excellent information, but here is a caution I posted in the other thread.

Although it is the best compilation I have seen in one place and is well worth the time to read, two things should be remembered when comparing the data:

1. It was not produced by an independent source. VIP Enterprises is selling an auxiliary system and has presented the data in a light most favorable to themselves. Example: The chart claims that no auxiliary system Applies Towed Brakes in true proportions (same as M/H). There are some manufacturers who would disagree with that statement.
   
   
2. The chart has not been revised in two years (last revision 1-1-02) and as such, some of the information is outdated. How much error in the chart this creates is not easy for me to determine. I would think the MSRP comparison is wrong. I know there are places that list optional equipment which is now standard.
   

Having done considerable research recently, I'm aware of other errors in the chart. For example: The chart claims that, as an option, BrakeBuddy has Automatic Operation with manual override. There is no manual override with a BrakeBuddy system.

Still the chart is worth the read.

[justlou]

Pulsar,
Additional information can be found at www.viprv.com, then select tow brake and then comparison chart. They compare 14 different braking systems.

[pulsar]

I’m not completely happy with the way I am using the word invasive. Invasive may have more of a negative connotation than inserting a T-connector in a vacuum line deserves. What do you think?

What do you think of the way I’m using the term permanent installation?

What other systems should be included? I have done research on RoadMaster’s BrakeMaster system and Blue Ox’s Apollo system. However, I feel the report has already grown unwieldy.

Walter, (Hutch1358)
As I stated in the original post, I don’t want this thread to advocate for or against any of the products. Certainly there is a valuable place for advocacy, but I want this thread to provide an overview of different systems to help forum members filter their choices. I would also like for the thread to be an objective foundation for future discussions. Since you have used the VIP system, can you help me with this outstanding question? Adjustments to the system from within the toad: The amount of force applied to the toad’s brake pedal arm is set with a pressure regulator on the actuator assembly. Confirmation or correction?

Thanks,
Tom

[ploiselle]

I am in the frustrating process of researching auxillary braking systems. I found draft very informative. The August 2003 issue of MotorHome magazine has an article on Dinghy Braking Systems that may be of help.

Does anyone have any information on the Roadmaster BrakePro(February 2004, MotorHome magazine, upsidedown page 60)? It looks very similar to the BreakBuddy or Appolo, but has proportional breaking. I sent RoadMaster an email requesting more information, but have not heard back from them yet. Camping World never heard of it and when I inquired at a RoadMaster dealer in my area, they tried to sell me a BreakBuddy. RoadMaster's website doesn't mention it.

Thank you for the great work!

[Hutch1358]

I would like to make a couple of comments on this very informative write up.

I had origionaly installed a VIP Tow Brake system in my Honda CRV. It took three overnight deliveries to replace the defective parts before I was able to get the system installed and operating (they claimed they had an employee that made a lot of mistakes). The retracted stroke on the piston is adjusted by a switch held in place with a set screw. If the set screw fails the piston retracts all the way and trys to tear the brake pedal out. Guess what, mine failed (they acknowledged the failure) and damaged a vehicle that at that time was two weeks old to the tune of $675. Even though they acknowledged the failure they would not reimburse me for any of the damage. The did give me the money back for the system. IMO a very poor way to do business.

For two years now I have had the SMI four wire system. Very pleased with it. One minor problem with a component and they overnighted a replacement. They have since made a couple of improvements and have offered to make the changes to my unit free of charge if I return it to them. Turn around would be three days. I have called a couple of times looking for information (new MH installation) and there technical dept. has been great to deal with. I would highly recomment there unit....Hutch

You wrote "Fred, Did I guess correctly that the Silent Partner uses accelerometers instead of a mercury switch? Anyone visiting their website would have a hard time determining that Stay-IN-Play is a variation that can be applied to either of three basic units. Determine if accelerometers are used is impossible to get from the website."

I can't locate the papers that came with my unit, but I read them all during the installation and I don't think it answered that question. I can say that when using the "real time" mode the control module applies the toad brakes when the coach brakes are applied and SUFFICIENT DECELERATION FORCE force is detected. It will also release the toad brakes when the deceleration force is reduced even if the coach brakes are still on. Now whether this implies accelerometer or mecury switch, I don't know. Since the sensitivy is adjustable I think it may be more than a mercury switch. I've sent an email to SMI asking this question. I'll let you know when I get an answer.
