A redundant brake unit for a motor vehicle comprises: an inlet port configured to receive fluid under pressure from an external source; an outlet port connected to a supply passage and configured for fluid connection to a wheel brake; a reservoir port connected to a return passage and configured for fluid connection to a fluid reservoir; a boost valve configured to selectively control fluid communication between the inlet port and the supply passage; and a pressure supply unit including a pump element configured to pump fluid between the return passage and the supply passage. The pump element has an inlet directly connected to the reservoir port with no actuated valves therebetween. A normally-closed valve and a throttle valve are disposed in a series configuration between the supply passage and the return passage, with the throttle valve being operable to control a fluid pressure in the supply passage.
