CAMPAIGN: CLUTCH CABLE/ BRAKE MASTER INTERFERENCE

GENERAL MOTORS HAS DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS ON SOME 1980 CHEVROLET CITATION MODELS. THE CLUTCH CABLE ON SOME 1980 CITATIONS EQUIPPED WITH A MANUAL 4-SPEED TRANSMISSION MAY RUB AGAINST THE MASTER CYLINDER BRAKE PIPE WHEN THE CLUTCH PEDAL IS OPERATED. OVER AN EXTENDED PERIOD OF OPERATION, THE INSULATION ON THE CLUTCH CABLE COULD WEAR THROUGH RESULTING IN A METAL TO METAL CONTACT; ALSO THE BRAKE PIPE CLEARANCE TO THE TRANSMISSION CASE, ENGINE COMPARTMENT SIDE FLANGE AND TRANSMISSION SELECTOR LEVERS MAY BE INADEQUATE. SHOULD THIS CONDITION EXIST, IT COULD EVENTUALLY RESULT IN THE FAILURE OF THE BRAKE PIPE CAUSING LOSS OF BRAKE FLUID AND THE CONSEQUENT PARTIAL LOSS OF BRAKING ACTION.

BECAUSE THESE VEHICLES ARE EQUIPPED WITH A DUAL BRAKING SYSTEM, A PART OF THE SYSTEM WILL REMAIN FUNCTIONAL, ALLOWING THE VEHICLE TO BE STOPPED, BUT OVER A GREATER DISTANCE. SHOULD A PARTIAL LOSS OF BRAKING ACTION OCCUR WHILE THE VEHICLE IS IN MOTION AT A TIME WHEN MINIMUM STOPPING DISTANCES ARE REQUIRED, A VEHICLE CRASH COULD OCCUR WITHOUT PRIOR WARNING.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
