Automatic, Truly Proportional Braking

BrakeMaster offers truly proportional, synchronized braking by connecting directly to your RV's air or air-over-hydraulic brakes. The air cylinder that attaches to your towed vehicle's brake pedal will apply your car's brakes at the same time and with the same intensity as you apply the brakes in the RV. To achieve this proportional braking, the BrakeMaster uses air pressure from your coach's brakes to depress the brake pedal in your towed car. The result is uniform, real-time braking that mirrors the slowing or stopping action of your coach.


Many other proportional systems activate the towed car's brakes based solely on inertia. With this kind of setup, any activity that affects the forward momentum of your towed car - from the coach actually braking, to driving over a pothole - can activate the supplemental braking system and apply your towed car's brakes. This potential for false braking, which can occur simply from driving over uneven terrain, can create a rough ride for you in the RV and can also wear out your towed car's brakes over time. The BrakeMaster is different, though. Because it is tied into your coach's brakes and is not dependent on inertia, this system activates only when you apply the brakes in your RV, so there is no false braking.


This braking system will work with almost any RV that has air or air-over-hydraulic brakes. It will also fit nearly any car, although a seat adapter may be required for installation in certain vehicles.


Installation and Easy Connection

The BrakeMaster connects directly to your RV's air or air-over-hydraulic brakes, making the installation on the RV side quite involved. An advanced mechanical background is required. Once you have successfully tapped into the RV's brakes, use the included hose to connect your RV brake line to BrakeMaster's actuating cylinder. A custom seat adapter (sold separately) is required to secure the cylinder to the floor in your towed car. If a custom bracket is not available for your application, then a universal floor plate (450650-01 - sold separately) can be used instead. The clamp on the opposite end of the cylinder attaches to your car's brake pedal. When you apply the brakes in your RV, air will travel from the RV to the cylinder. The cylinder will then transfer that air pressure to the actuating arm, which will apply the brake pedal in the towed car.


Once the BrakeMaster is completely installed, connecting and disconnecting is quick, easy, and requires no tools or adjustments. To disconnect the system, just remove the clamp from the brake pedal, unclip the cylinder from the mounting bracket, and disconnect the air hose. To connect again later, simply attach the clamp to the pedal, secure the cylinder to the bracket on your floor or seat adapter, and reconnect to the air hose.


Breakaway Device

BrakeAway

In the unlikely event that your vehicle separates from your motor home, the included breakaway system will give you peace of mind. Just mount the breakaway switch at the front of your towed car and wire it to both your battery and to the BrakeAway air reservoir. The air reservoir connects to the actuator that presses the brake pedal in your towed car. If your towed car separates from your motor home, the pin in the breakaway switch will be pulled out, which will send a signal to the BrakeAway to activate. The BrakeMaster actuator will then be signaled to press your towed car's brake pedal, bringing your vehicle to a stop.


Monitor Alerts

Most supplemental braking systems have methods of letting you know you when the system is activated, but they don't necessarily inform you of whether or not the brake pedal is being depressed. Such setups leave opportunities for false notification, which can be dangerous and potentially damaging. If the system activates but doesn't depress your car's brake pedal, then your RV's brakes will be taxed because they will have to brake for the towed car as well. On the other hand, if the system isn't properly positioned, it could be pressing your car's brake pedal continuously, which could damage your vehicle. BrakeMaster's system is different. The included LED monitor connects to your towed car's brake light switch. When your car's brake light goes on or off, so does the notification light. This way you'll always know whether or not your car's brake pedal is being pressed.

Hardest part was finding a place for the air reservoir, which I placed in front of the driver's side wheel, inside the fender liner of our 2018 Explorer. Can still reach the drain valve, worked great. Etrailer is awesome to work with!

Roadmaster was real slow with the delivery of the seat adapter. But Michael kept me informed all the way through to the delivery. etrailer is 5 stars all the way from start to finish. I look forward to using them in my orders to follow. Now for ROADMASTER products RM-643 safety cables quality is good work fine Delivery was fast RM-9160 brake master system Love this system instructions were easy to follow RM-15267 toad tail light/brake wiring good instructions for install RM-1550-1 base plate good instructions for install except you need to drill two 1/2'' holes you must measure and mark as there is no pilot hole. The whole system works great with the 2008 Honda Pilot RM-88189 seat adapter I have yet to install as I had to make up my own for the trip. I will say the seat adapter bracket is made just for the Honda and Acura, they had to make custom make. Thanks to all the car towed great for my first trip of 1,100 miles

Installation does take some time as you will have to find a good place to install the break away cylinder. I could not find any reference material for my application. 2018 Jeep Wrangler JL with the 2.0 liter engine. The only place I could find to install it was between the battery and the fender. If you are not mechanically inclined I would recommend having this installed by a professional.

Looks to be very complete and should work as intended. As of yet, have not installed and cannot comment as to whether it actually will work. Have confidence in the Roadmaster name and their products. Am not expecting any issues. (Just received yesterday, 01/28/21).

Got everything installed except the foot that mounts to the floor. It wasn't in the box. I called etrailer who contacted Roadmaster and they said they would ship and I should have in a couple of days. Installed everything else along with the tow bar and light kit. Followed all the instructions and all went smoothly with no issues. Just have to wait for the missing part to complete and test.
