The Even Brake from Roadmaster is a portable, compact, self-contained supplemental braking system that sits in front of the driver's seat of your towed vehicle. It easily attaches to the brake pedal and applies the brakes with a force that matches the intensity with which your motor home slows when you brake it. Do-it-yourselfers will love the quick and easy installation. Hookup and disconnect can be done in just a few minutes. The Even Brake is a comprehensive system and it includes an emergency breakaway kit and a wireless brake monitoring system.


Even Brake Breakdown

Automatic Proportional Braking

A proportional braking system ensures that your towed car's brakes are applied with an intensity that matches the slowing or stopping action of your towing setup. The result is improved control, better stopping, and less wear on the brakes of both your vehicle and your RV. Even Brake also automatically levels itself when traveling uphill, downhill, or on uneven ground. This automatic adjustment keeps the Even Brake level on all terrain so that it continues to brake proportionally and efficiently. It also helps to prevent any false braking, which can occur when traversing rough terrain.


The Even Brake uses an inertia sensor to detect deceleration. Once the rate of deceleration is determined, an electromagnetic proportional regulator inside the unit will release the amount of air pressure needed to apply the towed car's brakes with an intensity that matches.


Installation and Easy Connection

The ICX transmitter box, which connects to your towed car's brake light switch, will permanently mount beneath your dash. This box plugs into the Even Brake portable unit and then transmits information regarding system status and braking activity to the receiver that mounts in your RV. It also connects to the included breakaway system so that it can signal the Easy Brake unit to activate the towed car's brakes in the event of a breakaway. Minor modification may be required to route the breakaway harness through your car's firewall.


Once the ICX transmitter is installed, setting up the Even Brake is a breeze. Just situate the portable unit in your towed car between the driver's seat and the brake pedal. Because the unit relies on being level to function properly, it has 4 independently adjustable feet to keep it stable in cars with uneven floors. The seat brace also adjusts up or down to ensure a perfect fit and proper leverage when pressed up against the driver's seat. Once you have the unit properly situated, position the brake pedal clamp over the brake pedal. Plug the portable unit into the ICX transmitter and then into the 12-volt accessory outlet in your towed car, which will power the unit. Before towing, make sure you press the test button on the Even Brake so that the system can cycle to deplete any vacuum pressure in the brakes.


Brake Sensitivity Settings

The Even Brake allows you to fine-tune the braking sensitivity to fit your personal preference. By adjusting the sensitivity on the operating unit, you get to decide how intense the change in forward momentum must be for the electromagnetic valve to respond. Set the sensitivity low and the Even Brake will only respond when you forcibly step on your RV's brake pedal. Set the sensitivity high and it will respond when you merely tap your RV's brakes. The Even Brake saves your personal settings, making setup faster and easier.


Monitor Alerts

Even Brake Breakdown

The included monitor mounts in your RV and keeps you updated on the status of the Even Brake. This wireless system relies on the ICX transmitter, which is mounted in the towed car, to send signals to the monitor. Just plug the monitor into a 12-volt outlet in your RV for power.


Because the ICX transmitter connects to your car's brake light switch, it is able to transmit a signal that lets you know not only when the Even Brake has been activated, but also if your towed car's brake pedal has actually been depressed. It's possible that the Even Brake could be misaligned, or it could shift or creep during travel, and may be unable to appropriately apply the brakes. Poor positioning could cause the unit to either apply the brakes continuously or to not apply enough pressure to the pedal to activate the brakes at all. This could happen with any portable system. But because the Even Brake informs you of the braking activity of your car rather just the activity of the braking system, you will be able to tell when there is a problem so that you can correct the issue before damage to your car's brakes occurs.


The Even Brake monitor uses different colored LED lights, an LCD text display, and audible alerts to keep you informed about your braking setup. The 3 LEDs - green, yellow, and red - give you an easy-to-see visual reference to keep you updated on how the Even Brake is functioning and what it is doing.


While the LED light offers a quick reference of what the Even Brake is doing, the LCD display explains it in detail. Whether the system is ready for towing, informing you that it is applying the brakes in the towed car, or warning you of an emergency braking situation, the text display keeps you in the loop.


The audible alert sounds in the event of an emergency. This way you'll know if, for example, a breakaway has occurred, even if you aren't watching the monitor.

I ordered a complete towing package from etrailer for my Sprinter RV to tow a Hyundai Accent. The Roadmaster Even Brake was the supplemental braking system that etrailer recommended. The system has worked flawlessly. After the original set-up, it literally takes all but 2 minutes to either put in or take out and stores neatly in the trunk of my Accent when not in use. The instructions for use and adjustment are clear and easy to understand. After a year of use, I couldn't be happier with this system. 791212

Great product, but when ordering you need to request any updated supplemental technicians bulletins for your specific vehicle (my vehicle = 2015 Jeep Cherokee Trailhawk). Installation using the included product installation instructions exactly (not being told that there were updated technicians bulletins) caused the vehicle battery to run down to the point where I couldn't operate any vehicle electronics or start the vehicle. A call e-Trailer provided updated information. The manufacturer (Roadmaster) was aware of the issue and provided solution instructions. Had this been offered when ordered, I would have avoided having to deal with a dead battery and extra installation time. When installed using the updated information, the product works great. 174847

  • Is a Brake Lite Relay Required for 2018 Jeep Grand Cherokee Being Flat Towed
    I understand, there is a lot of components to flat tow a vehicle and even from year to year model changes can make a big difference. You do not need a brake lite relay for the Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 on your 2018 Jeep Grand Cherokee. That's because when you put your Grand Cherokee into "tow mode" the brake pedal does not provide any power to the brake lights.

  • Is Break Away Switch Required for Roadmaster Even Brake Supplemental Braking System
    To install the Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 you do need to use the break away switch. The break away harness will be connected to the ICX transmitter so the two are going to need to be used in conjunction with one another. The break away switch is also going to apply the brakes of your towed vehicle if for some reason the connection is lost with your motorhome which is a significant safety factor.
