Most Popular Proportional System for Jeep CJ-7

My husband installed this himself and it took a couple of weekends to finish. It works great and was the perfect solution for our flat-tow set-up.

I had my local Cadillac dealer install the braking system in my Mini and it was done perfectly. Now I just flip a switch and the braking system is activated. I did have them hook up an extra wire on the RV harness. They ran the center 12 volt source to the Mini battery. That way, the system doesn't drain the battery on long hauls. An interesting side note: the system takes an extra half second to release the brake pressure to the car after my RV brake pedal is released. Therefore, if the pressure is set too high, you feel the car putting significant drag on the RV. This really helped to setup the system initially and is a daily reminder that the system is working as a little bit of drag for a half second is normal.

Kit fits great! Hooked up a 2004 Workhorse to a 2002 Jeep Liberty. It might be preferable to be handy with some advanced mechanical skills and tools to install this efficiently. Directions are great but you do need to figure out your own locations for certain items like the break-away reservoir, compressor, routing lines and wires out of harms way, but not bad at all. Parts are great, everything there but added a couple different wiring splices of my own.

Your customer service leaves nothing lacking, and this follow-up from you is so out of character for the many web sites I have purchased from over the years. I am impressed by you and your company. I bought the tow bar and the brake system for my Equinox, and installed them my self (I am 70 years old) - and with your provided instructions and video, I had no problems (even though I was surprised by the number of parts and detail that went into the assemblies). Both systems have worked very well, with no problems. I am completely satisfied with them, and have told my friends and traveling acquaintances about your company. Thanks for your follow-up!

Lasted 1 year and started to intermittently stop working. We thought it was the power cord so we replaced it. Now, 2 years after more significant use, it doesn’t work. Actually had our tow vehicle crash into our rig breaking our etrailer tow bars, put a hole in our radiator, ruined the grill and fiberglass damage. If not for the upgraded chains we use replacing the cheap cables etrailer tow bars come with, our suv would have crashed into another car or worse rolled off the George Washington bridge! We were in heave NY traffic! Thankfully we got to the shoulder without damage to anyone else around us, BY drivers are not as mean as people say! Do NOT but etrailer tow bars or this brake buddy! Not worth the risk and look at the cost! I could see if we chose some cheap knockoff product, but this is significant money spent!! RV is a 2021 Tiffin Phaeton and etrailer tow bars are a year old.

Plug keeps getting loose on unit. I drilled a hole in the case and installed a tie wrap attaching wire to case no more movement of plug works great otherwise

Very touchy on where it is sitting on the floor in front of the seat. Must be lined up almost perfectly. Heavy and clumsy to get in and out and connected to brake pedal. Need to add an on/off switch to the power line on the controller otherwise it is transmitting a signal on Jeep brands all the time that interferes with the remote key lock. Quite disappointed with hit and miss braking operation while in use and sending braking signal to driver when it is not braking.

I bought a complete flat tow parts fir a jeep wrangler. I decided I could install myself. Your installation videos made it nearly a piece of cake. From a quote I got from a RV service business, I saved several thousand dollars installing myself. etrailer is the place to for your RV needs!

The Brake Buddy has been working great. I just wish they had made the plug a more standard mount. It doesn't fit the standard mount point on my Roadmaster baseplate. I had to make a little bracket to adapt it.

I choose the Brake Buddy Stealth for my 2021 Jeep Wrangler because I wanted a “stay in place” brake system and felt it would be a clean looking installation. I finished the toad side of the installation today and thought I’d leave some notes on what turned out to be a bigger project than I’d anticipated. Again, this is my experience on the 2021 Jeep Wrangler 2-door. Your experience on other vehicles may vary. I started this install after installing a Demco Tabless Base Plate. Right out of the blocks, there’s really no convenient location to mount the cable connector to the Demco baseplate. I chose to mount it to under side of the bumper on the driver’s side. To provide clearance and a route for the wires, I had to cut a notch into the plastic air dam. I used one of the already screw screw holes and used self tapping screws in the other three locations. For added strength I epoxied the connector to the bumper as well. Since the bumper would be unremovable if the connector were hardwired, I added a waterproof connector. The kit is stingy with wire lengths, so I substituted my own wire. The Stealth unit itself i mounted beneath the driver’s seat. Don’t be fooled into believing there is clearance when testing with the driver’s seat positioned for rear seat access. Once the seat is returned to normal operation it lowers a bit and the box keeps the seat from being move forehand aft. I solved the problem by installing 5/8” thick nylon washers under the rear end of the seat slides. I also cut away a bit of the carpet under the front, inboard corner of the box. You will need to remove the driver’s seat in order to attach the front screws of the box. Be sure to disconnect and isolate the neutral battery terminals to prevent inadvertent air bag discharge. After removing the interior trim from the A-pillar, the door sill, and the driver side foot well, The wiring and cable tucked nicely away along with the OEM wiring and wiring for my taillights. I mounted the pulley horizontally behind the brake pedal. Installing the vacuum pump was my biggest worry and challenge. Instructions are to zip tie it “somewhere”. That seemed pretty casual for a safety system. I chose, instead, to fabricate an aluminum bracket that attaches to the lip of the engine compartment and to the wheel well (this latter attachment point is necessary to keep the pump from vibrating). Finally, the kit comes with 3/8” fittings to tap into the brake booster vacuum lines. The Jeep, however, uses 8mm nylon tubing. Brake Buddy, via etrailer.com, stated that the tubing would stretch and all would be good. Again, this felt casual for a safety system. Instead, I purchased an 8mm check valve and a 8-6-8mm barbed tee through Another online retailer to do the job right. I had to heat the Jeep tubing to fit even the 8mm tee, so the is no way the larger 3/8” fittings would have worked. See photo of my finished vacuum line installation. Bottom line, it was a POA install, but looks great. Hopefully it will stop the Jeep when towing. I’ll find out soon. :D

The install on my Ford Maverick is clean and functional, so this is more of a customer service review... excellent customer service! During the 4-day towing set-up install, the forecast was for freezing temps and my rig was not winterized. I called in mid panic and the motorhome was moved indoors. A few months after using the tow set-up, a minor problem developed. I called and the CSR apologized and said, I can see how that might be frustrating, and a replacement cable (slightly longer) was sent free of charge.

The system works great! I was too intimidated by my coach's air brake system to attempt to install the line on the coach, so I had that done by a pro. But I did the rest of the install myself. It was straightforward, and the installation instructions were crystal clear. The product works great.

Works great with air brake system on my RV. Really like the plug-in and go. Moderately easy to install and had good installation instructions. Wished I had gotten the unit sooner. Tech staff were great at helping me locate main air supply on my rv. Would highly recommend. I installed unit on '23 Jeep Rubicon and 2003 40'Beaver motorhome.

I purchased this as part of a package which included; Hitch and wiring for my 2022 Equinox, Base plate, Tow Bar, brake System and connecting air hose, break away cables, LED tow lights with wiring harness, and a trickle charger to keep the Equinox battery from going dead while I was towing it behind my class A RV. I had etrailer do the install of all the components on my car and RV. All the workmanship was excellent and done in the amount of time they said it would take. Also because they did not have a video of this equipment being put on this year and model vehicle, I gave them permission to make a video(which added a extra day and a half to the install)and the installation was free. Everything has worked perfectly and I couldn't be happier. Etrailer is my go to for anything towing and also RV parts.

Upgraded from RVi3 system which was a portable unit and operated solely on inertia which in my experience only worked on moderate to hard braking. This system being a dual system works even with mild braking. I'm very happy with it. Installation took me several partial days (60+ yr old, moderate mechanical skills). The videos are very helpful and had one for my exact 2020 Jeep Wrangler. Installation is easy but access under the dash to install the air cylinder and a roadmaster brake switch is awkward and difficult. My biggest fear was the access there and cutting the vacuum line. The vacuum line turned out to be very easy. I had to adjust my brake light switch after installation when I tested the system. Everything is adjusted properly now and works as I hoped.

Take the time to really study the videos from etrailer and you’ll have no problems. Kit came well packaged with everything I needed. Hardest part was working under the dash…not a lot of room to work in a 2013 Honda CRV.

Andy was a great help to get my flat tow started on my Ford Ranger. I will go to my local auto electric buddy for the lights installation. Thanks Andy for your help.

I installed a battery charge line on my towed vehicle and had to leave the auxiliary switch on to get power to the Blue Ox I got 20 miles away and the battery was already below 10amps so has to disconnect the Blue Ox.
