Brake Fluid Level Switch

DESCRIPTION






The brake fluid level switch is located in the brake fluid reservoir of the master cylinder.

OPERATION
The purpose of the brake fluid level switch is to provide the driver with an early warning that the brake fluid level in the master cylinder fluid reservoir has dropped below a normal level. This may indicate:
- Abnormal loss of brake fluid in the master cylinder fluid reservoir resulting from a leak in the hydraulic system.
- Brake shoe linings which have worn to a point requiring replacement.
As the brake fluid drops below the minimum level, the brake fluid level switch closes to complete the red BRAKE warning lamp circuit. This will turn on the red BRAKE warning lamp. The master cylinder fluid reservoir should be checked and refilled to the full mark with DOT 3 brake fluid. If the brake fluid level has dropped below the add line in the master cylinder fluid reservoir, the entire brake hydraulic system should be checked for evidence of a leak.
