Brake Fluid Level Sensor/Switch: Description and Operation
How the Circuit Works
The brake system indicator light comes on to alert the driver that the parking brake is applied, or that the brake fluid level is low. It also comes on as a
bulb test when the engine is cranked.
Brake Fluid Level
The brake system indicator receives battery voltage through fuse 55 and the gauge relay. If the brake fluid level is low, the brake fluid level switch
closes, providing ground to the circuit. The brake system indicator light then comes on, alerting the driver to a low brake fluid level in the master
cylinder. (Check brake pad wear before adding fluid.)
