Cleaning and Inspection
Inspect brakelining wear. Replace riveted lining if it is
worn to within 1/32 inch (0.79 mm) of the rivet heads.
Replace bonded lining if it is worn to a total thickness of
approximately 1/16 inch (1.58 mm) or less.
Inspect the lining wear pattern. If wear is uneven
across the width of the lining, replace the lining and
check the drum for distortion and runout. Inspect the
lining for cracks, charred surface, or broken rivets. Re
place the lining if contaminated with brake fluid, axle
lubricant, or similar contaminants or if the lining exhib
its any of the conditions described previously.
Inspect the adjusting screw spring, return springs,
holddown springs, actuating lever return spring, and
automatic adjuster spring. Replace any springs that are
distorted, broken, discolored (overheated), or lack
tension.
Inspect the parking brake lever, automatic adjuster
lever and pivot, and actuating lever for wear and de
fects. Replace levers if bent, broken, or excessively
worn.
