Cleaning & Inspection

  1. Boot, piston seal, rubber bushings, and sleeves must be replaced each time caliper is overhauled. Clean all other parts in denatured alcohol, then dry using dry filtered compressed air.
    NOTE: Using lubricated shop air will leave a film of mineral oil on metal parts, which may damage rubber parts upon contact at reassembly.

    Check mounting bolts for corrosion, breaks in plating, or other damage.

    NOTE: Do not attempt to clean bolts, replace them.
  2. Check outside diameter of piston for scoring, nicks, corrosion, worn or damaged plating. If surface defects exist, replace piston.
    CAUTION: Do not attempt to refinish piston with abrasives.

    Check piston bore in caliper for scratches or other damage. Minor scratches or corrosion may be polished clean with crocus or emery cloth. Thoroughly clean bore after polishing. Replace caliper if corrosion is not easily cleaned.
