What is the purpose of the air brake system in commercial vehicles?

The air brake system in commercial vehicles is primarily designed to provide safe and reliable braking. This system operates using compressed air, which allows for more effective and consistent braking performance, especially in large vehicles that require significant stopping power. The use of air pressure is particularly important in heavy trucks, as it can handle the weight of the vehicle more efficiently than traditional braking systems. The air brake system also includes safety features like the spring brake, which automatically activates in the event of air pressure loss, ensuring that the vehicle can stop safely under such circumstances.

While aspects like fuel efficiency, driving comfort, and noise pollution can be considered in the design and operation of vehicles, they are not the main functions of the air brake system. The focus of this system is to ensure that the vehicle can stop safely and effectively under various conditions, which is crucial for the safety of both the driver and other road users.
