United States 79V177000
WHITE MOTOR CORPORATION
The problem
THE INVOLVED VEHICLES DO NOT CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS", IN REGARD TO DEFECTIVE BRAKE APPLICATION AND IMPROPER RELEASE TIME. 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.
What owners should do
DEALER WILL EITHER REBUILD THE VALVE OR PERMANENTLY DISABLE THE ANTI-LOCK SYSTEM WITHOUT CHARGE.
