Owner Letter

General Motors has determined that some 1992 G-Vans produced at the Scarborough Assembly plant and equipped with vacuum power brake systems (JS5/JB7) have an incorrect brake pedal assembly. This incorrect brake pedal assembly has a pushrod pin that is both too small and installed in the incorrect location relative to the brake pedal pivot. The incorrect location of the push rod pin causes an increased brake pedal ratio that results in a decreased master cylinder stroke. Although a vehicle with a decreased master cylinder stroke will meet the full system stopping requirements of Federal Motor Vehicle Safety Standard (FMVSS) 105, "Hydraulic Brake Systems" it will not meet the partial system failure requirements. A further reduction of braking ability at a time when partial system failure has occurred could result in a vehicle crash without prior warning.
