Brake Shoes, Linings & Calipers, Inspection

Remove wheels and inspect brake disc, caliper and linings. The wheel bearings should be inspected at this time and repacked if necessary. Do not get any grease on the linings.
Do not replace individual pads or replace pads on one wheel of an axle set alone, as braking performance will be adversely affected.
If a visual inspection does not adequately determine the condition of the linings, the brake shoe and lining assemblies should be removed and inspected. If shoes do not require replacement, reinstall them in their original positions. Brake shoes and linings should also be replaced if cracked or damaged.
If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.
