What does brake chamber do?
What does brake chamber do?
Air brake chambers are round metal containers, located at each wheel, where compressed air is converted into mechanical force to apply the brakes and stop the vehicle. The pushrod and a lever – called a slack adjuster – link the brake chamber to the brake assembly (which contains the brake drum or disc).
What happens when you pressurize the spring brake chamber?
In the diagram to the left, the spring brake chamber has been pressurized, and the spring brake diaphragm has compressed the heavy duty spring, which allows the push rod to release the pressure on the slack adjuster arm, which releases the parking brake. When you release the parking brake, you actually pressurize the spring brake chamber.
What is the rear spring brake air chamber called?
Rear Spring Brake Air Chamber The rear brake air chamber is more complicated because it serves two purposes. One part of this dual chamber is called the spring brake chamber and the other part is called the service brake chamber. The service brake chamber is what activates when you step on the tractor brake pedal.
What are the components of a brake chamber?
The components of a brake chamber are housed in a round canister sealed by a clamp. Brake chambers come in two main types, service chambers and spring brakes. Service chambers apply the brakes when air is applied to the chamber and return via an internal spring to a released position when the air is removed.
How does the push rod work in an air brake chamber?
It has a single diaphragm which pushes the push rod to the right when air enters into the chamber from the air inlet. All of these brake chambers have sizing information. The larger the chamber size, the more force the chamber can generate.

How does a push rod air brake chamber work?
The push rod and air chamber as present as usual, but behind this chamber is a second one which contains a powerfully coiled braking spring on a solid plate, much like the plate the push rod ends in. It’s kept in check by a latch which connects directly to the parking break lever in the driver’s cab.
