Summary

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.

Consequence

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

Remedy

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