99V351000·SERVICE BRAKES, AIR1999-12-14

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. THERE IS INTERFERENCE BETWEEN THE AIR BRAKE S-CAM AND THE END OF ONE OF THE KNUCKLE STUDS. AS THE BRAKE SHOE LINING WEARS, THE S-CAM ROTATION MAY BE LIMITED BY THE INTERFERING KNUCKLE STUD. IF THE S-CAM CAN NOT ROTATE THROUGH ITS FULL RANGE OF MOTION, THE BRAKING FORCE CAN NOT BE FULLY TRANSMITTED FROM THE BRAKE SHOE LININGS TO THE BRAKE DRUMS.

RiskTHIS COULD RESULT IN A LONGER STOPPING DISTANCE OR A DRAGGING BRAKE CONDITION.

FixDEALERS WILL SHORTEN THE INTERFERING KNUCKLE STUD TO ELIMINATE THE CLEARANCE PROBLEM.

RiskWITHOUT SUFFICIENT TORQUE ON THE GUIDE PAWL CAP SCREW, THE BRAKES COULD GRADUALLY LOSE ADJUSTMENT, INCREASING THE VEHICLE STOPPING DISTANCE.

FixDEALERS WILL CHECK THE TORQUE ON THE AUTOMATIC SLACK ADJUSTER GUIDE PAWL. IF THERE IS NO TORQUE, THE BRAKES WILL BE ADJUSTED AND THE GUIDE PAWL WILL BE TIGHTENED TO 15-20 FT. LBS.
