NHTSA recalls, safety ratings, and consumer complaints for the 1983 GMC C7.
Component: SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
THE DUAL AIR RESERVOIRS OF SOME TRUCKS WERE EQUIPPED WITH CARBON STEEL SPRINGS INSTEAD OF STAINLESS STEEL SPRINGS, AS INTENDED. THE CARBON STEEL SPRING IS MORE SUSCEPTIBLE TO RUSTING THAN THE STAINLESS STEEL SPRING. THIS RUSTING COULD CAUSE THE CHECK VALVE TO FAIL, CAUSING TOTAL LOSS OF FRONT AND REAR BRAKES.
Remedy: THE AIR TANK WILL BE INSPECTED AND, IF NECESSARY, THE AIR VALVE WILL BE REPLACED WITH ONE CONTAINING A STAINLESS STEEL SPRING.
Component: SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS
THE FRONT AIR BRAKE HOSE MAY CONTACT THE INNER FENDER ON THE LEFT AND/OR RIGHT SIDES OF SOME TRUCKS. IN SOME INSTANCES, THE BRAKE HOSE MAY RUB THROUGH, RESULTING IN A LOSS OF AIR PRESSURE UPON BRAKE APPLICATION. CONSEQUENCE OF DEFECT: BRAKE HOSE MAY RUB THROUGH CAUSING AIR PRESSURE LOSS WHEN BRAKES ARE APPLIED AND REDUCED BRAKING ABILITY. A REDUCTION OF BRAKING ABILITY AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
Remedy: INSTALL NEW BRAKE CHAMBER SUPPORT BRACKETS, BRAKE LINE ELBOWS, AND AIR BRAKE HOSES, AS NECESSARY.
