No Braking

No braking

When the driver is not braking the car, the braking system is in stand-by mode: that is, the master cylinder is in its resting position and the connection between the brake fluid reservoir and the rest of the hydraulic system is open. The system is then completely unpressurized. In the hydraulic unit valve block, the hydraulic valves are in their resting position: that is, the inlet valves are open and the outlet valves are closed.
