A brake chamber is a component of an air brake system on a heavy duty vehicle, such as a truck or bus. It is a cylindrical chamber that contains a diaphragm, which is connected to the brake pedal or lever. When the brake pedal is pressed, air is supplied to the brake chamber, which pushes the diaphragm outward and applies pressure to the brakes.
A repair kit for a brake chamber typically includes the necessary seals, gaskets, and other components to rebuild or repair the brake chamber. It may also include instructions for how to properly install the repair kit. If you are in need of a repair kit for your brake chamber, you should consult the owner's manual for your vehicle or contact a mechanic or parts supplier for assistance in obtaining the correct kit.
