CAMPAIGN: PARKING BRAKE CABLE DISCONNECTED FROM BRAKE
Models: 1988 Grand Prix and Cutlass Supreme, Equipped With a Manual Transmission
DEFECT INVOLVED:
General Motors of Canada has determined that certain 1988 Pontiac Grand Prix and Cutlass Supreme model vehicles may fail to conform to the requirements of Federal Motor Vehicle Safety Standard (CMVSS) 105, "Hydraulic Brake System." In some of these vehicles, the parking brake cable may be disconnected from the left rear brake caliper. With a disconnected cable, the parking brake cannot be properly applied, and the vehicle will not meet the grade holding requirements specified in CMVSS 105.
To prevent the possibility of this condition occurring, Dealers are to install a retainer on the left rear caliper of those vehicles on which the cable is not already retained with a cotter pin and adjust the parking brake system using the procedure described in this bulletin. In addition, to improve durability of the parking brake pedal assembly, a new one will be installed.
