I have a brake pro that the previous owner of my motorhome included when I bought it. I have a new Jeep I'm considering putting it in but have read some bad reviews - mainly related to battery drain. Is it worth fooling with?
There is a thread on here from 2 years ago talking about an air leak on the cylinder - that might be your issue as well. Sounded like parts were hard to find even then.
