Which device is used to pass the pressure from hydraulic cylinder towards brake? Correct Answer Valves

Valves are used to pass the pressure from hydraulic cylinder towards brake. When the valve is closed, then it isolates the break from the hydraulic cylinder. Thus, they control the pressure supplied to the brakes. The function of Pump in the automatic brake system is to restore pressure to the hydraulic brake after the valves have released it.
