Air Brake Chamber

Velvac®

An air brake chamber is a component of the braking system in a truck that converts compressed air into mechanical force to activate the brakes. It is typically made up of a diaphragm, pushrod, and return spring housed in a metal casing. When air pressure is applied to the diaphragm, it pushes the pushrod out which in turn activates the brake shoes or pads. The return spring then pulls the pushrod back when air pressure is released, allowing for smooth operation of the brakes. The 030019 model number refers to a specific type of air brake chamber used in heavy-duty trucks and trailers.
