Abstract
A brake system comprises a master cylinder, a first brake cylinder, a second brake cylinder, an electronically-controlled pressure generating unit distinct from the master cylinder, a first hydraulic circuit in selective fluid communication with the master cylinder and the first brake cylinder, a second hydraulic circuit in selective fluid communication with the master cylinder and the second brake cylinder, and a controller. In a first mode, the controller is operable to actuate the electronically-controlled pressure generating unit to deliver hydraulic fluid pressure to the first brake cylinder and the second brake cylinder proportional to an input. In a second mode, the controller is operable to actuate the electronically-controlled pressure generating unit to deliver hydraulic fluid pressure to the first hydraulic circuit and the first brake cylinder and the master cylinder is in communication with the second hydraulic circuit to deliver hydraulic fluid pressure to the second brake cylinder.
