A wedge brake chamber is a type of brake chamber used in heavy-duty vehicles, such as trucks and buses. It is called a "wedge" brake chamber because it uses a wedge-shaped actuator to push the brake shoes out against the brake drum. This type of brake chamber is known for its durability and ability to generate high braking force. Wedge brake chambers are commonly used in air brake systems and are typically found on the rear wheels of a vehicle.
