Abstract
A braking assembly for providing a braking force to a wheel brake of a vehicle based upon receipt of an electrical brake signal is provided. The brake assembly comprises an actuator including a motor that applies and releases a piston within an actuator body. The actuator is fluidly connected to a wheel brake whereby the wheel brake can be applied and released. A solenoid valve is interposed between the actuator and the wheel brake on a primary fluid path for opening and closing the fluid connection. A step piston is placed within a secondary fluid path between the actuator and the wheel brake and operates to momentarily increase fluid displacement applied to the wheel brake when the solenoid valve closed.
