Inspection

1. If any parts are of doubtful strength or quality due to heat discoloration, or are worn, replace them.
2. Inspect wheel cylinder dust boots for signs of excessive wear or damage.
3. Inspect auto adjuster gear for smooth operation over full length.
4. Clean adjusting gear components in denatured alcohol.
5. Apply suitable lubricant to adjuster screw threads, inside diameter of socket and socket face. Adequate lubrication is achieved when a continuous bead of lubricant is at open end of adjuster nut and socket when threads are fully engaged.
6. Clean dirt and/or rust from brake drum, backing plate and all other components. Do not use compressed air or dry brush to clean brake parts. Many brake parts contain asbestos fibers which, if inhaled, can cause serious injury. Clean brake parts with a water soaked rag or a suitable vacuum cleaner to minimize airborne dust.
7. Ensure adjuster gear turns freely on adjuster screw.
