A brake system for actuating front and rear wheel brakes includes a reservoir and a master cylinder operable by actuation of a brake pedal connected to the master cylinder to generate brake actuating pressure at a first output for hydraulically actuating the front wheel brakes. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating the front wheel brakes. A pair of rear brake motors selectively electrically actuate respective rear wheel brakes. An electronic control unit controls at least one of the power transmission unit and the rear brake motors. A two-position three-way valve is hydraulically connected with the master cylinder and the power transmission unit and with the front wheel brakes. The three-way valve selectively controls hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to at least one of the front wheel brakes.
