Disc Brake Caliper: Disassembly
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, 2004 Ford Cutaway, and 2003 Ford RV Cutaway. 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 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.
- 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.
