The compressor is a vital component in an air brake system, as it is responsible for generating the compressed air needed to charge the air tanks. This pressurized air is essential for the proper functioning of the air brake system, as it allows for the activation of the brakes when the driver applies them. The compressor continuously replenishes air in the tanks to maintain adequate pressure, ensuring that the system remains ready for operation at all times.

Without the compressor functioning effectively, the air tanks would not charge properly, leading to insufficient air pressure for braking and potentially compromising the safety of the vehicle. Other components, such as brake valves, serve different functions in controlling the air flow and braking process but do not generate or supply the compressed air required for the system to operate efficiently. The air filter ensures that the air entering the system is clean, and while the hydraulic pump might be utilized in hydraulic brake systems, it is not applicable in air brake systems. Therefore, the compressor is essential for charging the air tanks and maintaining the integrity of the braking system.
