The short version

PACCAR INCORPORATED reported a problem with the supply check valve. Here is what owners need to know.

WHAT

IN EXTREMELY COLD CONDITIONS, THESE BENDIX RELAY VALVES MAY POTENTIALLY DEVELOP INTERNAL LEAKAGE. INTERNAL LEAKAGE CAN LEAD TO AIR PRESSURE BEING DELIVERED TO AFFECTED PRIMARY OR SECONDARY BRAKE CAUSING CONTINUOUS BRAKE APPLICATION.

WHY IT MATTERS

UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE BRAKES TO OVERHEAT AND LEAD TO A FIRE. UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE DRIVER TO LOSE CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH.

WHAT TO DO

PACCAR WILL NOTIFY OWNERS, AND PROVIDE A TEMPORARY REPAIR UNTIL BENDIX DEVELOPS A PERMANENT REMEDY, free of charge.
