ALSO, THE ANTI-LOCK VALVES WERE MANUFACTURED WITH AN ANTI-LOCK PISTON WHICH, WITH EXTENDED USE, MAY STICK. THIS PREVENTS AIR FROM BEING DELIVERED TO THE AIR BRAKE CHAMBERS SUPPLIED BY THESE VALVES.
The fix
DEALER WILL EITHER REBUILD THE VALVE OR PERMANENTLY DISABLE THE ANTI-LOCK SYSTEM WITHOUT CHARGE.
VEHICLE DESCRIPTION: TRUCKS.SYSTEM: SERVICE BRAKES; RELAY VALVE.CONSEQUENCES OF DEFECT: THIS CONDITION WOULD RESULT IN A PARTIAL LOSS OFBRAKING ACTION AND EXTENDED VEHICLE STOPPING DISTANCES. THIS SITUATION COULDLEAD TO AN ACCIDENT.
