Abstract
A brake system includes a plunger assembly for actuating wheel brakes during a normal brake apply. The plunger assembly includes 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. A second piston is slidably mounted within the housing for pressurizing a second fluid chamber in the housing. A pump-less control valve arrangement includes a first control valve regulating the flow of fluid between a first fluid chamber and the first wheel brake. A second control valve regulates the flow of fluid between a second fluid chamber and the second wheel brake. An isolation valve arrangement switches the brake system between the normal braking mode and the manual push-through mode.
