The primary purpose of an air brake system is to slow down or stop a vehicle by using compressed air. In heavy vehicles, like trucks and buses, air brake systems are essential because they provide the necessary power to operate the braking mechanism effectively. When braking is required, compressed air is stored in tanks and released to engage the brake shoes or pads, applying pressure to the brake drums or discs. This allows for a powerful and reliable stopping force, crucial for safety in large vehicles, especially when carrying heavy loads.

The air brake system is designed to maintain efficiency and reliability under various driving conditions, which is why it is favored over other braking systems in larger vehicles. While electrical energy generation and enhancing vehicle speed are related to other systems in a vehicle, they do not align with the fundamental objective of an air brake system. Monitoring engine performance is pertinent to the engine management systems, but does not play a role in the braking function.
