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.
