CAMPAIGN: BRAKE PIVOT BOLT LOOSE-PONTIAC EAST ASSEMBLY
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1990 C/K 15-35 trucks. These vehicles may have a loose pivot bolt holding the brake pedal to its support bracket. In a few cases, the pivot bolt was only hand started into the bracket weld nut without engaging the locking material on the bolt. In certain other cases, the bolt was fully engaged into the weld nut, but below the specified torque. It is possible for the bolt to disengage from the nut resulting in loss of braking action. If this condition occurs while the vehicle is in motion, a vehicle crash could occur without prior warning.
To prevent this condition from occurring, dealers will torque the brake pedal pivot bolts to specification.

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.
