Roadmaster auxillary toad brake inJeep Wrangler

I have a 2000 Jeep Wrangler and use a Brake Buddy. I have the pressure set at 45psi. This might be a starting point for you.

After getting equipment set up, you will probably need someone to ride in the Wrangler to observe how the braking device operates during various stops and make appropriate adjustments.

Good luck-- Mick

Can't help but was wondering does your 2015 wrangler leak like sieve?
I just got a 2015 and get puddles of water every time it rains.

Mike, I have a hard top with removable panels above the driver and passenger. We have been in driving rain where we had to pull off the road. No leaks, quiet to ride in with no wind whistle either. If you have a soft top I could understand some leakage, but not with a hard top. An idea for you to try and find the leaks in hard top would be to pressurize the interior cabin. The cabin is vented to the outside thru the rear door. If I remember correctly a one way flapper would have to be taped open to the position. Then hook up a shop vac with the hose coming off the exhaust giving pressure. Tape this hose to the vent behind and under th spare tire rack. Turn on the vac and pour soapy water over the jeep and look for bubbles. Now that you found the source of the leak fixing it is your problem. Only idea would be black silicone. Good luck.
Blessings; Keith

Yes mine is a hard top with the freedom panels. Funny my 2001 with a soft top never leaked.
My leaks are coming from on top of both front doors. I guess it's I common problem with them. When I told the service lady at jeep about the leaks she said "it's a jeep they all leak"

Mike, sent you a PM; Keith

Our's don't leak. Convenient excuse from a dealer.

I had the Roadmaster aux brakeing system several years ago on a new chevy pickup. Left home to snowbird but never unhooked the truck until I reached Vegas. Applied the brakes and the pedal went almost to the floor. Drove it about a block and the pedal went up and down when applying the brakes. Tore it down at my son's house in his shop and discovered the pads were worn through and the rotors were blue and warped from the heat created. Had to replace the pads and rotors on my new truck which kinda upset me GRRRR. The problem was whenever I used the exhaust brake on grades it also applied the toad brakes so after 1000 miles of this the brakes were ruined. Sold this piece of junk on ebay for less than half what I paid. Been using the M&G brake system for 8 years on 3 different trucks and it's been flawless and only takes 5 seconds to hook up. Good luck with yours.
