A brake system for actuating a plurality of wheel brakes comprising first and second pairs of wheel brakes includes a reservoir and a motor-driven master cylinder operable during a normal non-failure braking mode to generate brake actuating pressure at first and second MC outputs for hydraulically actuating the first and second pairs of wheel brakes. A secondary power transmission unit is configured for selectively providing pressurized hydraulic fluid at first and second PTU outputs and includes an electric PTU motor configured to selectively pressurize the hydraulic fluid by transmitting rotary motion to at least two pump pistons. The secondary power transmission unit is indirectly fluidly connected to the reservoir to selectively draw hydraulic fluid therefrom.
