Cleaning & Inspection

The boot, piston seal, rubber bushings, and sleeves are to be replaced each time caliper is overhauled. Clean all other parts in denatured alcohol. Dry parts with dry, filtered, compressed air.

NOTE: Using lubricated shop air will leave a film of mineral oil on metal parts. This may damage rubber parts upon contact after reassembly.

Check mounting bolts for corrosion, breaks in plating, or other damage. Do not attempt to clean bolts; replace them. Check outside diameter of piston for scoring, nicks, corrosion, worn or damaged plating. If surface defects exist, piston must be replaced.

NOTE: Refinishing piston with abrasives is not acceptable.

Piston bore must also be checked for major defects. Bore is not plated; therefore, minor corrosion can be polished with crocus or emery cloth. Thoroughly clean bore after polishing. Replace caliper if bore corrosion is not easily cleaned.
