SOUTHWEST TRUCK BODY CO.
The problem
ANTI-LOCK BRAKE FAILURE COULD OCCUR DUE TO EXPOSURE TO HIGH CONCENTRATIONS OF FLUID CONTAMINANTS WHICH MAY COLLECT IN THE TRAILER BRAKING SYSTEM. THIS CONDITION COULD RESULT IN THE PISTON STICKING IN THE TRAILER ANTI-LOCK VALVE. CONSEQUENTLY, NO AIR WILL BE DELIVERED TO THE BRAKE CHAMBERS SUPPLIED BY THE ANTI-LOCK VALVE. LACK OF AIR TO THE AIR CHAMBERS MAY RESULT IN A "NO BRAKE" CONDITION ON THE AFFECTED AXLE(S).
What owners should do
DEALER WILL INSPECT AND, IF NECESSARY, INSTALL REPLACEMENT VALVES WITHOUT CHARGE TO OWNER.
