and flush with fresh brake fluid. Hone or replace as necessary.
Magnets and Magnet Arms- Inspect magnets for wear. Inspect magnet arms for
loose or worn parts.
Shoes and Linings- Inspect visually. Replace if the lining is worn to

less, contaminated with grease or brake fluid, or abnormally scored or gouged.
Hardware- Check all hardware. Check shoe return spring, hold down springs, and
adjuster springs for stretch or wear. Replace as required. Service kits are available.
Drums- Check drums for scoring, cracking, or uneven wear. Machine drum surface
only if under maximum diameter. Replace as necessary. See page 17 for more informa-
tion.
Brake Lubrication
Moving brake components should get a light film of high temperature grease or anti-
seize compound. These areas include the brake anchor pin, the actuating arm bushing
and pin, and the areas on the backing plate that are in contact with the brake shoes and
actuating lever arm.
BRAKE LINING CONTAMINATION!
Do not get grease or oil on the brake linings, drums, or magnets.
