Brake Shoe: Testing and Inspection
^
Inspect rear brake shoes and linings for excessive lining wear or shoe damage. If lining is damaged or worn within 0.79mm (1/32 inch) of the rivet
heads on riveted linings, it must be replaced. Replace any rear brake shoe and lining that has been contaminated with oil, grease or brake fluid.
^
Replace rear brake shoe and lining in axle sets only. Never replace just one rear brake shoe and lining of a brake assembly. Replace both primary
and secondary shoes. Prior to replacement of lining, brake drum diameter should be checked to determine that brake drum diameter is within
specification. If braking surface diameter exceeds specification, the brake drum must be replaced.
^
Check condition of rear brake shoes and linings, retracting spring, hold-down springs, and brake drum for signs of overheating. If rear brake shoe
and lining metal parts have a slight blue coloring, indicating overheating, retracting and hold-down springs should be replaced. Overheated springs
lose their tension and could allow new rear brake shoe and lining to drag and wear prematurely, if not replaced.
