Air Brake Valves and Master Cylinders

Air brake valves and master cylinders are important components of the air brake system on a heavy goods vehicle (HGV).Air brake valves control the flow of compressed air to the brake actuators, which apply the brakes on the vehicle. There are different types of valves such as the relay valve, the governor, and the foot valve, which control the pressure in the brake system and provide the driver with the ability to apply the brakes in various situations.

The master cylinder is a hydraulic device that converts the force applied by the driver's foot on the brake pedal into hydraulic pressure. This pressure is then sent through the brake lines to the brake actuators at the wheels, causing the brakes to be applied.Both valves and master cylinder are crucial for the safe operation of the vehicle, and they need to be checked and maintained regularly. If they are malfunctioning, the brakes can fail, resulting in an accident.
