Bypass Condition

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check the brake hydraulic system for leaks or insufficient brake fluid. Repair as necessary.
  2. Observe the brake fluid level in the brake master cylinder reservoir while the brake pedal is slowly applied and released. If the brake fluid level drops when the brake pedal is applied and rises when the brake pedal is released, but the net brake fluid level remains unchanged, the brake master cylinder is bypassing. Repair or install a new brake master cylinder. Refer to HYDRAULIC BRAKE ACTUATION .
