NHTSA Campaign 78V232000

SERVICE BRAKES, AIR:DISC:CHAMBER

Issued by WALKER EQUIPMENT · Reported Oct 20, 1978 · 37 vehicles affected

What's wrong

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.

Remedy

THE DEFECTIVE VALVE WILL BE REPLACED WITHOUT CHARGE.
