Air chambers are _________.

Air chambers are used to convert compressed air into mechanical force to apply the brakes. They are located at each wheel end and are connected to the brake shoes or brake pads. When the driver presses the brake pedal, air is sent to the air chambers, which causes the pistons inside the chambers to extend and apply the brakes. Air chambers are an important part of the braking system and are essential for the safe operation of commercial vehicles.
