Our goal here at rvAutoPark.com, is to supply information that will help coach owners troubleshoot and repair their Chevy P32 Workhorse Chassis, J71 Ver II Auto Park Brake System, as well as other versions. Is your AutoPark actuator cylinder leaking? - - we can help. We realize however, that in some cases and for whatever reason, there are times when a coach owner cannot make their own repairs. In these situations, we often will suggest that maybe you can enlist the aid of a friend or family member - - They need not be a master mechanic - - just the normal skills of a do-it-yourselfer will usually get the job done. Once you understand how your Auto Park brake system works, troubleshooting and repair will get easier.

Even more importantly, it provides real attention-getting evidence of an imminent parking brake lockup. This is a device that most motor home owners should be able to assemble and install themselves – - with parts costing less than 20 dollars.
Need Help with locked up AutoPark Parking Brake System?
If your coach was built between (about) mid 1989, on up through (about) 2006, it may be equipped with a AutoPark parking brake system. This is a system which can automatically apply your parking brake when you put the gear shift lever into PARK. The earlier versions of this system rely on pressure from the power steering system to release this brake, and the later versions have their own separate pump and reservoir. Either of these setups can malfunction and cause application of the parking brake - - anywhere, anytime.
