Abstract: A vehicle braking system includes a first wheel cylinder, a second wheel cylinder, a master cylinder including a first master cylinder chamber in fluid communication with the first wheel cylinder via a first circuit and a second master cylinder chamber in fluid communication with the second wheel cylinder via a second circuit, and an electronically controlled pressure generating unit separate from the master cylinder. The vehicle braking system is operable to provide braking in a first configuration in which the electronically controlled pressure generating unit pressurizes fluid, through the master cylinder, in the first circuit, to the first wheel cylinder. In the first configuration, the electronically controlled pressure generating unit pressurizes fluid in the second circuit to the second wheel cylinder, bypassing the master cylinder.
