What is the function of the air compressor in an air brake system?

The function of the air compressor in an air brake system is to generate compressed air for the brakes. This compressed air is essential as it is stored in the air tanks and is used to activate the brake chambers, which then engage the brake shoes or pads to slow down or stop the vehicle. The air compressor continuously replenishes the air supply, ensuring that the braking system operates efficiently and reliably.

The air brake system relies on this compressed air to function, making the compressor a crucial component. Without adequate compressed air, the braking system would not engage properly, leading to a potential failure to stop the vehicle safely. Thus, the ability of the air compressor to produce and maintain the necessary pressure is vital to the overall reliability and safety of air brake systems.
