A brake system for selectively actuating at least one of a pair of front wheel brakes and a pair of rear wheel brakes of a vehicle, one of which is hydraulically actuated and the other of which is electrically actuated, includes a reservoir. First and second integrated control units are in fluid communication with the reservoir and respective ones of the hydraulically actuated wheel brakes. The first and second integrated control units have first and second power transmission units connected to first and second electronic control unit, respectively. Each electronic control unit is configured to control a corresponding power transmission unit and a selected one of the electrically actuated wheel brakes on a contralateral side of the vehicle from the selected one of the hydraulically actuated wheel brakes which is actuated by the power transmission unit.
