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.
DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE LEFT REAR BRAKE ADJUSTER ASSEMBLY AT NO CHARGE.
VEHICLE DESCRIPTION: BUS CHASSIS, MEDIUM AND HEAVY TRUCK CHASSIS.SYSTEM: SERVICE BRAKES; LEFT REAR BRAKE ASSEMBLY.CONSEQUENCES OF DEFECT: AS THE CLEARANCE BECOMES LARGER, THE SERVICE BRAKINGCAPABILITY IS REDUCED PROGRESSIVELY. INCREASED PEDAL TRAVEL WILL ALSO OCCUR.THE ADVERSE AND PROGRESSIVE REDUCTION IN BRAKING PERFORMANCE COULD AFFECTSTOPPING DISTANCE AND COULD CREATE THE POTENTIAL FOR AN ACCIDENT.NOTE: SOME IMPROVEMENT IN BRAKING PERFORMANCE MAY BE OBTAINED BY PUMPING THEBRAKE PEDAL.
