Air brake systems are commonly used in heavy trucks and buses, providing reliable stopping power through compressed air. The system includes service brakes, parking brakes, a control pedal, and an air storage tank. For the parking brake, a disc or drum brake mechanism is held in place by spring pressure. To release it, air pressure must be applied. When the driver presses the brake pedal, compressed air (typically around 100–120 psi or 690–830 kPa) is directed to the brake chamber, activating the brakes.
Most truck air brakes are drum-based, though there's a growing trend toward using disc brakes for improved performance. The air compressor draws filtered air from the atmosphere and compresses it into high-pressure reservoirs at about 120 psi (830 kPa). Drivers can monitor air pressure via a gauge inside the cabin, often with warning lights or sounds. A mechanical "wig wag" may also drop into view when pressure drops below a safe level.
Setting the parking or emergency brake releases the air in the system, allowing the spring-actuated parking brake to engage. A sudden loss of air pressure will immediately activate the spring brakes, ensuring safety even in emergencies.

A compressed air brake system is divided into two main parts: the supply system and the control system. The supply system compresses, stores, and delivers high-pressure air to the control system and other auxiliary systems like gear shift controls or clutch assistance. This ensures smooth and safe operation of the vehicle under various conditions.
