Abstract
A vehicle braking system having a master cylinder and first and second hydraulic braking circuits including respective first and second wheel cylinders for braking first and second wheels. The master cylinder has first and second outlets, first and second pistons associated with the first and second outlets, a fluid reservoir and a master cylinder input member provided with a mechanical coupling to drive the first piston and configured to drive the second piston only through movement of hydraulic fluid. The second hydraulic braking circuit is selectively disengageable from the master cylinder via a separation valve. The second hydraulic braking circuit includes a line coupling a suction side of a pump with the master cylinder reservoir. A pressure control valve is configured to modulate the amount of fluid drawn from the reservoir by the pump. The second hydraulic braking circuit is coupled to the first outlet of the master cylinder.
