The present invention relates to a break system. The brake system includes first and second wheel brakes and a brake pedal unit including a housing and a pair of output pistons slidably disposed in the housing, The pair of output pistons are movable to generate brake actuating pressure at first and second outputs for actuating the first and second wheel brakes, respectively, during a manual push through mode. A plunger assembly for actuating the first and second wheel brakes during a normal brake apply includes a housing and a motor mounted on the housing for driving an actuator. A first piston is connected to the actuator. The first piston is slidably mounted within the housing for pressurizing a first fluid chamber in the housing. The first fluid chamber is in communication with the first wheel brake. A second piston is slidably mounted within the housing for pressurizing a second fluid chamber in the housing. The second fluid chamber is in communication with the second wheel brake. A pump-less control valve arrangement includes a first control valve regulating the flow of fluid between the first fluid chamber and the first wheel brake. A second control valve regulates the flow of fluid between the second fluid chamber and the second wheel brake. An isolation valve arrangement switches the brake system between the normal braking mode wherein boost pressure from the plunger assembly is supplied to the wheel brakes, and the manual push-through mode wherein brake actuating pressure from the brake pedal unit is supplied to the wheel brakes.
