Brake Fluid Level Sensor/Switch: Testing and Inspection

Brake Fluid Level Switch Test





Check for continuity between the terminals (A) with the float in the down position and the up position.
^ Remove the brake fluid completely from the reservoir. With the float down, there should be continuity.
^ Fill the reservoir with brake fluid to the MAX (upper) level (B). With the float up, there should be no continuity.
