CERTAIN AIR BRAKE ANTI-LOCK MODULATORS COULD MALFUNCTION DURING OPERATION OF THE ANTI-LOCK SYSTEM. A NYLON PISTON WITHIN THE MODULATOR AIR VALVE SYSTEM CAN SWELL FROM EXPOSURE TO SYSTEM CONTAMINANTS. CONTINUED EXPOSURE MAY CAUSE THE PISTON TO SWELL TO THE EXTENT THAT INTERFERENCE WITH THE CYLINDER WALL WILL RESULT, CAUSING MOMENTARY STICKING OR A PERMANENT JAM. THIS CAN RESULT IN TEMPORARY OR PERMANENT LOSS OF BRAKING FOR THE AFFECTED AXLE.

Remedy: THE PISTONS IN THE VALVE PORTION OF THE MODULATORS WILL BE REPLACED WITH PISTONS THAT DO NOT SWELL WHEN EXPOSED TO AIR BRAKE SYSTEM CONTAMINANTS.

Reported: 1983-03-22 (March 22, 1983) · Model years: 1982

SOME OF THE INVOLVED VEHICLES MAY HAVE BEEN BUILT WITH LEFT REAR BRAKE ASSEMBLIES THAT WERE INCORRECTLY PRODUCED AND MAY HAVE ONE OR TWO AUTOMATIC BRAKE ADJUSTERS THAT WERE INTENDED FOR RIGHT REAR BRAKE ASSEMBLIES. THE ADJUSTER WORKS BACKWARDS AND INCREASES THE CLEARANCE BETWEEN THE BRAKE LINING AND DRUM, INSTEAD OF MAINTAINING IT.

Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE LEFT REAR BRAKE ADJUSTER ASSEMBLY AT NO CHARGE.

Reported: 1985-12-20 (December 20, 1985) · Model years: 1984, 1985

THE HYDRAULIC PARKING BRAKE CONTROL VALVE MAY INADVERTENTLY ACTIVATE DUE TO MOMENTARY PRESSURE DISRUPTIONS WITHIN THE SYSTEM AND CAUSE THE PARKING BRAKE TO BE APPLIED, STOPPING OR SLOWING THE TRUCK UNEXPECTEDLY. CONSEQUENCE OF DEFECT: THIS UNEXPECTED STOPPING OR SLOWING OF THE TRUCK MAY INCREASE THE RISK OF A REAR END COLLISION SINCE THE BRAKE (STOP) LIGHTS ARE NOT ACTIVATED. ALSO, ON CERTAIN ROAD CONDITIONS THIS OCCURRENCE MAY RESULT IN LOSS OF VEHICLE CONTROL WHICH WOULD LEAD TO AN ACCIDENT.

Remedy: REPLACE THE PUSH-PULL TYPE BRAKE CONTROL VALVE WITH NEW OVER-CENTER CAM TYPE VALVES.
