Most Popular Brake Buddy for Jeep JL Wrangler

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

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

This was a tight fit in my 2001 Wrangler. The seat has to be all the way back. I also had to remove my weather tech floor mat and put in a 3/4” board to raise the front legs more than fully extended. It seems to be working fine now, I just towed it from Santa Fe, NM to Tucson, AZ with no issues. I ordered the battery charge line kit and the breakaway kit. I found it bothersome that all used different color wires for positive, ground etc.

Installation was a bit challenging, but the ETrailer viedos were great to get me through the harder areas. The brake Buddie works great, though becase of my Jeep configuration (notmuch room) it is somewhat difficult with the linkage but I'm getting better hooking it up with experience. Happy with purchase. THANKS for asking. AL
