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 MAX (upper) level (B). With the float up, there should be no continuity.
