Abstract
A master cylinder having first and second pressure chambers located parallel to each other and having first and second pistons, respectively, for pressurizing the parallel chambers and supplying pressure fluid to first and second brakes, and a third chamber with a third piston, the third piston being driven by an input shaft to the master cylinder for pressurizing the third chamber, the third chamber being connected to a third brake and to the first and second pistons of the parallel chambers, where the third piston abuts a balance arm which is connected to the first and second pistons for manual operation of the two pistons when a loss of pressure in the third chamber results.
