Question: 1 / 400

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

To reduce noise during braking

To generate and maintain air pressure

The brake compressor in an air brake system primarily functions to generate and maintain the air pressure needed for the braking system to operate effectively. This is essential because air brakes rely on compressed air to apply the brakes, which enables the vehicle to stop safely and efficiently. The compressor draws in air from the atmosphere, compresses it, and sends it to an air storage tank, ensuring a sufficient supply of pressurized air for braking actions. This pressurized air is then released to engage the brakes, allowing for reliable and consistent stopping power.

While other components in the braking system may be responsible for noise reduction, heat absorption, or managing brake lining wear, these tasks do not fall under the responsibility of the brake compressor. Instead, the compressor's critical role in maintaining adequate air pressure is fundamental to the overall functionality of the air brake system.
