Plug-and-play: this permanent system gets you automatic braking with a one-and-done installation. Actuator box installs out of your way under the front seat. Adjustable pressure setting for comfortable braking. Charges car battery while towing.

Specs:
A braking system is a must when towing a vehicle behind your motorhome. Without it, the weight of the towed car can create a safety hazard, strain your RV's brakes, and affect its the warranty of both your car and motorhome. Most states legally require a supplemental braking system, so if you don't use one and you end up in an accident (which is more likely since your RV takes longer to come to a full stop), your insurance and liability headache just doubled. You also won't have any breakaway system; if there's an accidental disconnect, there's nothing to bring your car to a stop.
The InvisiBrake is a permanent braking system, which means that it's a one-and-done. Once it's installed, there's no more setup that you have to do. When you plug in the power cord at the front of your vehicle, the system automatically turns on. Just like that, you're ready to flat tow.
While the components are installed permanently in your RV and toad, they remain concealed and inconspicuous. None of them will interfere with normal driving, and most of the time they are invisible.
This system will apply the brakes in your toad (towed vehicle) every time you hit the brakes in your RV. It will detect the brake light signal from your motorhome and trigger the system to the settings you pre-programmed.
The braking pressure of the InvisiBrake can be adjusted from 5 psi to 80 psi depending on the weight/size of your toad and your preferences. A higher pressure will brake your car with more force - a good fit for a heavy vehicle - and a lower setting is good for a small vehicle. 60 psi is the recommended default setting, but you can tweak it to suit your individual setup.
The adjustable pressure setting is also an important safety feature for a car with active or continuous-power-assist brakes, such as hybrids. A car with active/continuous-power-assist brakes has pressure in the brake lines even when the ignition is off, so a braking system could apply excessive pressure and potentially cause damage. By lowering the setting (20 psi is recommended), you can use the InvisiBrake with active brakes.
The pressure setting needs to be adjusted only once, during the initial installation, at which point you can test the system at different settings to determine which feels best. Once you have it set, it does not have to be readjusted, so your system is always ready to go.
Most often, the InvisiBrake actuator box installs beneath the driver seat of your toad, neatly tucked out of your way. You can, however, install it anywhere in your car that's convenient for you, such as in the trunk, as long as you can still access the adjustment knob.
A bracket and cable pulley will install on the arm of your vehicle's brake pedal. This will not interfere with normal braking function and does not have to be adjusted or removed. There will be lots of wiring to do as well, with connections made to the battery, breakaway switch, and tail lights. But once it's done, your braking system is always ready to go.
This is a tough installation, with several points that need careful precision to get right. Depending on the vehicle, it can be challenging to find a place to fit the actuator box, and you have to be sure the cable pulley will meet the brake pedal at the right angle to function properly. There's a good chance you'll be pulling up carpeting and removing panels to get the wiring and cable run. Check out one of our installation videos to see if this install is in your comfort zone! Otherwise you can take it to a professional to get it installed.

Thanks for the feedback and review Ken. I wanted to let you know that I have included a link to one of our installation videos and at about the 15 minute mark there are some details about installing the monitoring system in the RV.

A year later and Im still in love with the Roadmaster tow bar & base plate and InvisiBrake braking system. We just got back from a road trip that started around Seattle down to Bryce canyon and back. The tow bar and brake system worked flawlessly, I could not be more pleased. Also, recently I traded in the first Jeep that I installed this system on for a newer Jeep. Knowing that I would be towing the new Jeep as well, I wanted to uninstall the base plate and brake system from my old Jeep and reinstall them on the new. The process went very well, actually faster than the first time I installed it. So, bottom line is that Im very pleased with this set up and would recommend it highly.

You are welcome to return this InvisiBrake system however I wanted to let you know that while most of the time the InvisiBrake actuator box installs beneath the front seat of the towed car it does not have to be installed there. It can be installed anywhere in the towed car that is convenient as on as you can still access the adjustment knob.

Most excellent products and customer service. I had purchased a few different items from eTrailer and found that there were a couple of missing items. Without question or hesitation, they were in shipping and satisfying my problem. After I got into the project, I found the missing items and notified eTrailer of my error. I cannot say enough good things which describes the excellent customer service, product knowledge and assistance they offer their customers and potential customers.

This Invisi brake system works GREAT. VERY simple to install if you read the instructions. Still have not seen a better deal than what Etrailer gave me.
Do you have a question about this Flat Tow Brake System?

Still the same, works well, though the annoying clicking sound in the Jeep has not gone away. I have to wonder if other Jeep Patriot owners have solved it.
