Wheel Cylinder

2007 Ford Fusion SEL, 2.3 Z, StandardSECTION Wheel Cylinder
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: It is not necessary to do a complete brake system bleed if only the wheel cylinder was disconnected or installed new.
  1. Remove the bleeder screw cap and place a box end wrench on the wheel cylinder bleeder screw. Attach a rubber drain hose to the disc brake caliper bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.
  2. Have an assistant pump the brake pedal at least 2 times and then hold firm pressure on the brake pedal.
  3. Loosen the wheel cylinder bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the bleeder screw.
    • Repeat until clear, bubble-free fluid comes out.
    • Refill the brake master cylinder reservoir as necessary.
  4. Tighten the bleeder screw and install the bleeder screw cap.
    • Tighten to 5 Nm (44 lb-in).
