Brake Master Cylinder - Bypass Condition

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the master cylinder. For additional information, refer to BRAKE SYSTEM INSPECTION .
  2. Disconnect the brake tubes from the master cylinder.
  3. Plug the outlet ports of the master cylinder.
  4. NOTE: Make sure that the outlet port plugs do not show signs of leakage.
  5. Lightly apply the brakes and hold for 10 seconds. Release the brakes and then reapply with heavy force. If brake pedal height cannot be maintained, the brake master cylinder has an internal leak and a new brake master cylinder must be installed.
