Brake Fluid Level Sensor/Switch: Testing and Inspection

Brake Fluid Level Switch Test





1. Remove the reservoir cap (A). Check that the float (B) moves up and down freely; if it doesn't, replace the reservoir cap assembly.
2. Check for continuity between the terminals with the float in the down position (C) and the up position (D):
^ With the float up, there should be no continuity.
^ With the float down, there should be continuity.
