Cleaning & Inspection

  1. Clean all parts in brake fluid only. Check caliper bore for wear, rust, corrosion or other damage. Minor deposits or scratches can be removed with fine emery cloth. Check caliper mount for wear, cracks or other damage. Replace if defective.
    NOTE: Piston surfaces are plated. Pistons must be replaced if corroded or worn. Do not polish with emery cloth. Use DOT 3 or higher rated brake fluid.
  2. Check piston for rust, wear or damage. Replace if defective. Replace piston seal, dust seal, adjusting nut cup, and push rod "O" ring during overhaul.
