Defect 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.

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

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