Brake Shoe: Testing and Inspection
NOTE: Replace any rear brake shoe and lining that is defective. Replace lining in axle sets only. Never replace just one shoe of a brake assembly.
Replace both leading and trailing shoes on both sides.
PRE-CHECKS
-
Check the brake backing plate for damage. If any damage is found, replace the brake backing plate as described.
-
Prior to replacement of lining, check drum diameter to determine that brake drum diameter is within specification. If braking surface diameter
exceeds specification, brake drum must be replaced.
OVERHEATING INSPECTION
-
Check condition of rear brake shoes and linings, brake shoe retracting spring, brake shoe hold-down springs and brake drum for signs of
overheating.
-
If rear brake shoes and linings have a slight blue coloring, indicating overheating, brake shoe retracting spring and brake shoe hold-down springs
should be replaced. Overheated springs lose their pull and could cause new rear brake shoe and lining to wear prematurely if they are not replaced.
INSPECT BRAKE LINING
-
Inspect brake shoe and linings for peeling, cracking, or extremely uneven wear on the lining.
-
Inspect the lining for normal wear. If the lining material is less than 8 mm (0.125 inch), the rear brake shoes and linings must be replaced.
-
Replace any brake shoe and lining that has been contaminated with oil, grease or brake fluid.
