I have a 1999 Pace Arrow 37 ft. While driving down I-10, the brakes decided to apply themselves and I was forced to pull over as the coach came to a stop. I sat for 10 minutes with the engine shut off. The pressure in the system released and I was able to drive from Westlake, LA. to just east of Hammond, LA. when it happened again. I did the same thing and got it home. The brake pad aroma was pretty serious each time. I then brought it to Big Wheel in Hammond, LA. where they have replaced the brake lines, calipers pads, rotors, master cylinder, hydrobooster, ABS pump, and the power steering pump. They hgave bled and re-bled the brakes and still haven't cured the problem. Tim says he even has the Auto-park system disengaged. Still the brakes are locking up. Thankfully, the warranty I purchased with this coach when I bought it in July 2008 is covering this. What could this be? What has my mechanic missed? My coach has been sitting in the shop since March 25, 2009 and it is hurricane season here in Louisiana. Please help!!
I am scared by this. The problem is probably as easy as the rod between the brake peddel and the booster is the wrong length or the actuator rod thing is that operates the master from the booster is the wrong length. The brake peddle could also be held down by a badly adjusted brake light or similar switch. Either way the brakes are over heating due to not releasing properly. Whether there is a valve or the new booster is difective the problem should be traceable and repairable. So the real question is does the system require a bleader to be opened to completly release the brakes or not. That should be easily checked by the repair shop. I have seen one unit with this symptom that came and went that turned out to be a weak brake peddle return spring. But this is pretty obvious as the brake lights wouldnt turn off either. Good Luck
I agree with BUBBA, check for fluid flowing back in the master cylinder after pumping the brake pedal, if they stay on, open the bleeder, if they release check the rubber hose going to the wheels(they may de-laminate inside) hook a bangie cord to the brake pedal to pull it back & try it(return spring may be broken). There must be something which keep the fluid from coming back to the master cylinder, as the brake apply as you're driving, if it would be pressure from power steering pump by-passing in the booster, it would apply itself standing still with the engine running.

HEY MINUTE!!!!!!
What happen with big wheel? they don't know how to test caliper? If they retract with a screwdriver & no leak they're good, "replaced the brake lines, calipers pads, rotors, master cylinder, hydrobooster, ABS pump, and the power steering pump" Are they milking the insurance cie? or they don't know?
