What Are the Different Air Brake Parts?

Air brakes can handle larger loads, which is why they're used in heavy-duty vehicles, such as trucks. The air brake parts use compressed air to transmit pressure from the brake pedal to the braking mechanisms.

Several parts comprise the air brake system and work together to ensure efficient braking. The compressor is responsible for compressing the air needed for the braking system.

Its air dryer removes moisture and contaminants from the compressed air before releasing it into the system.

Your air brake system also includes a governor that regulates the air pressure in the system. The governor ensures that the pressure remains within a safe range to prevent any malfunction in the braking system.

Connected to the brake valve, the brake pedal regulates airflow to the brake chambers. Pressing the brake pedal will make the brake valve release the compressed air, which causes the brake chamber to expand and apply pressure to the brake shoe. The brake shoe then presses against the wheel, causing it to slow down or stop.

Brake chambers convert the compressed air into mechanical force to apply the brakes. The slack adjuster is a mechanism that ensures the brake shoes are in the correct position and maintain the correct clearance between the shoe and the wheel.

Proper maintenance and inspection of these air brake parts are essential to prevent any malfunction and ensure the safety of the driver and other road users.
