Question: 1 / 400

What is the function of a brake chamber in air brake systems?

To increase the braking distance

To convert air pressure into mechanical force to apply the brakes

The function of a brake chamber in air brake systems is to convert air pressure into mechanical force to apply the brakes. When the driver actuates the brake pedal, air is supplied to the brake chambers, which contain a diaphragm. The diaphragm moves in response to the air pressure, creating force that is transmitted through a push rod to activate the brake mechanism. This process is essential for the effective operation of air brakes, allowing for controlled braking and stopping of the vehicle.

The design and operation of the brake chamber are crucial because they harness the power of compressed air, which is a common and effective source of force in heavy-duty vehicles. Understanding this function helps technicians diagnose braking issues and maintain the air brake system effectively.
