ON CERTAIN MEDIUM AND HEAVY DUTY TRUCKS, A BRASS FITTING CONNECTS THE DOUBLE CHECK VALVE TO THE BRAKE RELAY VALVE. WITH CERTAIN INPUTS TO THE VEHICLE, THE WEIGHT OF THE CHECK VALVE ON THE FITTING CAN CAUSE THE ASSEMBLY TO RESONATE. THE SUBJECT VIBRATION CAN CAUSE EXCESSIVE STRAIN LEVELS IN THE FITTING, WHICH COULD EVENTUALLY FATIGUE AND FAIL.
IF THE FITTING BREAKS, THE REAR SERVICE BRAKES WILL CEASE TO OPERATE WITHOUT WARNING, RESULTING IN AN EXTENDED STOPPING DISTANCE, INCREASING THE RISK OF A CRASH.
DEALERS WILL INSTALL A KIT TO REMOUNT THE DOUBLE CHECK VALVE WITH A FLEXIBLE HOSE ON THE MAJORITY OF VEHICLES. ON A SMALL NUMBER OF UNITS WITH CLEARANCE ISSUES OR TRACTION CONTROL, A KIT WITH A NEW RELAY VALVE THAT HAS A BUILT-IN DOUBLE CHECK VALVE WILL BE INSTALLED. OWNER NOTIFICATION BEGAN SEPTEMBER 11, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.
ALSO, CUSTOMERS CAN CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT '1-888-327-4236'.
