Disc Brake Caliper: Disassembly
- Remove caliper. See DISC BRAKE CALIPERS & PADS under REMOVAL & INSTALLATION. Drain fluid from caliper. Secure caliper in a vise. Place a block of wood between caliper and piston(s). See Fig 1. Apply low air pressure to brake hose inlet. Air pressure forces piston(s) outward.CAUTION: DO NOT place fingers between wood and piston as piston leaves caliper.
- 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.
