Brake Master Cylinder - Normal Conditions
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The following conditions are considered normal and are not indications that the brake master cylinder is in need of service.
Condition 1: During normal operation of the brake master cylinder, the fluid level in the brake master cylinder reservoir falls during brake application and rises during release. The net fluid level (such as after brake application and release) remains unchanged.
Condition 2: Fluid level decreases with pad wear.
