Disc Brake Caliper: Disassembly

  1. Remove caliper. See DISC BRAKE CALIPERS & PADS  under REMOVAL & INSTALLATION.
  2. Drain fluid from caliper.
  3. Secure caliper in a vise. Place a block of wood between caliper and pistons. See Fig 1.
    4. WARNING: DO NOT place fingers between wood and piston as piston leaves caliper.
  4. Apply low air pressure to brake hose inlet. Air pressure forces piston(s) outward.
  5. If piston is jammed or seized and does not come out easily, use a brass hammer to lightly tap caliper while applying air pressure. DO NOT pry piston from bore. After piston comes out, remove seal and dust boot. Discard seals and boots.
