Disc Brake Caliper: Disassembly
WARNING: This page is about a different car, the 2004 Ford Ranger, 2003 Ford Ranger, and 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use same disassembly procedures for single and dual piston calipers.
- Remove caliper. See 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.
- 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(s) comes out, remove seal and dust boot. Discard seals and boots.
WARNING:
DO NOT place fingers between wood and piston(s) or caliper as piston(s) leaves caliper.
