THE AUTO PARK BRAKE ON OUR 1992 SAFARI MOTORHOME ON A CHEVY P30 CHASSIS LOCKS UP WHEN PUT INTO PARK AND WILL NOT RELEASE. MORE SIGNIFICANTLY THE AUTO PARK BRAKE ATTEMPS TO LOCK WHILE IN MOTION. AFTER REVIEWING THE WWW, I HAVE LEARNED THIS IS A COMMON PROBLEM THAT MANY RVERS FACE. THE GMC WORKHORSE DEALER THAT IS RESPONSIBLE FOR THIS CHASSIS CANNOT REPAIR THE PROBLEM. GM DOES NOT APPEAR TO PROVIDE A SOLUTION. MANY RVERS ARE REPORTING THAT THEIR "SOLUTION" IS TO DISABLE THE PARKING BRAKE. THIS IS OBVIOUSLY UNDESIRED.*AK
