BRAKE Warning Indicator
WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster BRAKE warning indicator illuminates when the parking brake is applied, or when there is a low brake fluid level. The parking brake switch and the brake fluid level switch are hardwired to the instrument cluster. The parking brake switch provides a ground to the instrument cluster when the parking brake switch is applied. The brake fluid level switch provides a ground to the instrument cluster when the brake fluid level is low or when the electrical connector is disconnected.
