The primary purpose of the air brake system is to provide effective and safe braking power for heavy vehicles. Air brakes are specifically designed to manage the substantial stopping power required for large vehicles such as trucks and buses. This is crucial because these vehicles have much greater mass and inertia compared to standard passenger vehicles. The design of the air brake system allows for better modulation and control, ensuring that the driver can apply the brakes smoothly and effectively, particularly when dealing with the demands of weight and gradient changes.

Effective braking not only improves safety for the driver and others on the road but also helps to prevent accidents by allowing for quicker and more reliable stops in emergency situations. The use of compressed air for braking provides consistent performance even under varying conditions, making it essential for the operation of heavy vehicles. Other functions, such as enhancing driving comfort or increasing fuel efficiency, may be secondary benefits but do not define the primary function of the air brake system.
