Brake System
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The brake system warning indicator has a dual function. It illuminates when the parking brake is applied or when a low brake fluid condition exists in the brake master cylinder reservoir. The brake system warning indicator will illuminate when there is a pressure differential between the front and rear brake hydraulic systems.
