Operation:
- Air Pressure Application: When the driver applies the brake pedal, it triggers a valve that allows compressed air to flow from the air reservoir to the brake chamber.
- Caliper Actuation: The compressed air enters the brake chamber, which then pushes a piston or diaphragm. This movement forces the brake pads within the caliper to press against the rotating brake disc.
- Friction and Heat: The contact between the brake pads and the disc generates friction, converting kinetic energy into heat and thereby slowing down or stopping the vehicle.
- Releasing the Brake: When the brake pedal is released, the air pressure is vented from the brake chamber, allowing a return spring to retract the piston or diaphragm. This action releases the brake pads from the disc.
