BRAKE Warning Indicator

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. 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.
there is low brake fluid level.
the brake fluid level switch is disconnected.
an electronic brake distribution (EBD) concern exists.
a loss of communication between the ABS module and the instrument cluster occurs.

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 an open circuit or if the switch is disconnected. The base brake system and the EBD system are monitored by the ABS module. When a concern exists with the base brake system or EBD, the ABS module provides a signal to the instrument cluster through the communication network. The instrument cluster turns the BRAKE warning indicator on or off, according to the monitored data.
