Defect description
ON CERTAIN HEAVY DUTY TRUCKS, THE BOLTS AND LOCKING NUTS USED TO HOLD THE BRAKE SPIDERS OR BRAKE ANCHOR PLATES TIGHT TO THE AXLES WERE UNDER-TORQUED ON THE RIGHT SIDE OF THE VEHICLES. IF THE CLAMP LOAD ON THE BOLTS IS NOT SUFFICIENT, THE ANCHOR PLATE MAY MOVE WHEN THE BRAKE IS APPLIED IN EITHER THE FORWARD OR REVERSE DIRECTION.
Safety risk
THIS MOVEMENT COULD CAUSE INDIVIDUAL BRAKE COMPONENTS TO FAIL OR EVENTUALLY FATIGUE ALL THE ANCHOR PLATE MOUNTING BOLTS. IF ALL THE BOLTS BREAK DUE TO FAILURE, A COMPLETE LOSS OF BRAKING AT A WHEEL END COULD OCCUR.
Manufacturer remedy
DEALERS WILL INSPECT AND TIGHTEN ALL SUSPECT BOLTS. NEW WHEEL SEALS AND NEW BOLTS WILL BE INSTALLED WHERE APPLICABLE. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING DECEMBER 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.
