With Antilock Brakes

The master cylinder is a standard tandem design with the exception of central valves that are used in conjunction with existing compensation ports. The center valve is a spring loaded ball and seat design which is unseated by a stop in the master cylinder when brakes are released.

A fluid level switch is located in the master cylinder fluid reservoir. The switch closes when low fluid level is detected, and the FLS-1 turns on the warning lamp. This will not disable the ABS system.
