Cleaning and Inspection

Inspect brake linings for excessive wear, damage, oil, grease or brake fluid contamination. If any of the above conditions exist, brake linings should be replaced as an axle set to maintain equal braking forces. Examine brake shoe webbing, hold-down and return springs for signs of overheating indicated by a slight blue color. Any component which exhibits overheating signs should be replaced. Overheated springs lose their pull and could cause brake linings to wear out prematurely. Inspect all springs for sags, bends and external damage and replace as necessary.

Inspect hold-down retainers and pins for bends, rust and corrosion. If any of the above is found, replace as required.
