Disc Brake Caliper: Disassembly
WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2003 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- 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 pistons. 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 comes out, remove seal and dust boot. Discard seals and boots.
WARNING:
DO NOT place fingers between wood and piston as piston leaves caliper.
