BRAKE WARNING SWITCH

The switch activates a light on the dash panel to indicate that one of the hydraulic systems has failed. There are two basic types of switches.

On most models, the brake warning switch is of the latching type. If a pressure loss occurs in one side of the system, the piston in the valve is forced toward the failed side where it ...
