What is the role of brake chambers in an air brake system?

To monitor engine temperature

To convert air pressure into mechanical force for braking

The role of brake chambers in an air brake system is to convert air pressure into mechanical force for braking. This process is essential for the function of air brakes, which rely on compressed air to create the force necessary to engage the brakes effectively. When the driver applies the brakes, air pressure from the system is directed into the brake chambers. Inside these chambers, the air pressure forces a diaphragm to move, which then activates the push rod mechanism that applies pressure to the brake shoes or pads against the brake drum or rotor. This mechanical action results in the slowing or stopping of the vehicle.

This conversion of air pressure into mechanical force is crucial because it allows for a reliable and powerful braking action, especially in large vehicles such as trucks and buses that require significant stopping power. Understanding this principle helps grasp how air brake systems differ from other braking systems that might rely solely on hydraulic pressure or friction mechanisms.
