2. Base Brake Function
During normal braking, NO VALVE 1, 2, and 3 are in the ON status and closed. The pump either turns on or off according to the chamber status.
At this point, the NC VALVE 1 and 2 become ON and opened. The pressure generated by the pump is supplied to the boosting chamber and pressure is formed in the cylinder.
