Abstract
An anti-lock braking system includes a master cylinder for supplying pressurized fluid to the vehicle brakes and a pump which operates during anti-lock control to supply fluid during brake pressure build cycles. A braking circuit includes decay valves and build valves to control communication of fluid pressure to the vehicle brakes in response to commands generated by an electronic control unit. A braking source control valve responds to signals generated by the electronic control unit to switch communication of fluid pressure to the braking circuit between the master cylinder and the pump.
