THE PISTON IN THE ANTILOCK VALVE COULD STICK DUE TO EXPOSURE TO HIGH CONCENTRATIONS OF FLUID CONTAMINANTS THAT MAY COLLECT IN THE TRAILER BRAKING SYSTEM. CONSEQUENTLY, NO AIR WOULD BE DELIVERED TO THE BRAKE CHAMBERS NORMALLY SUPPLIED BY THAT VALVE. THIS COULD RESULT IN A "NO BRAKE" CONDITION ON THE AFFECTED AXLES. THIS CONSTITUTES A NON-COMPLIANCE TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS".
THE DEFECTIVE VALVE WILL BE REPLACED WITHOUT CHARGE.
VEHICLE DESCRIPTION: TANK TRAILERS.SYSTEM: SERVICE BRAKES; ANTILOCK AIR VALVE.CONSEQUENCES OF DEFECT: LOSS OF BRAKING CAPABILITY COULD RESULT IN A VEHICLEACCIDENT.NOTE: UNTIL THE VALVE IS REPLACED, ANY FLUIDS SHOULD BE DRAINED FROM THE BRAKESYSTEM DAILY AND FLUIDS SHOULD NOT BE ADDED DIRECTLY INTO THE BRAKE LINE.
