The defect
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.
The remedy
THE DEFECTIVE VALVE WILL BE REPLACED WITHOUT CHARGE.
