The brake system includes a pedal, a pedal simulator, and a brake pedal unit. The brake pedal unit includes an input piston connected to the brake pedal for operating the pedal simulator during a normal braking mode. The brake pedal unit further includes first and second output pistons actuated by the input piston during a manual push through mode such that the first output piston generates brake actuating pressure at a first output of the brake pedal unit, and the second output piston generates actuating pressure at a second output of the brake pedal unit. The brake system further includes a hydraulic pressure source for supplying fluid at a controlled boost pressure, and a hydraulic control unit adapted to be hydraulically connected to the brake pedal unit and the hydraulic pressure source. The hydraulic control unit includes a slip control valve arrangement and a switching base brake valve arrangement for switching the brake system between the normal braking mode, wherein boost pressure from the hydraulic pressure source is supplied to first and second vehicle brakes, and the manual push through mode wherein the brake actuating pressure from the first and second output pistons is supplied to the first and second vehicle brakes, respectively.
