Cleaning & Inspection

  1. Replace boot, piston seal, rubber bushings and sleeves each time caliper is overhauled.
  2. Clean all parts in denatured alcohol. Dry parts using clean dry compressed air. Lubricated shop air will ruin rubber parts upon contact at reassembly.
  3. Check mounting bolts for corrosion, breaks in plating or other damage. Replace bolts if damaged in any way. DO NOT attempt to wire brush or clean them.
  4. Check outside diameter of piston for scoring, nicks, corrosion, or worn and damaged plating. If surface defects are visible, replace piston. DO NOT attempt to refinish with abrasives.
  5. 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.
