Our Euclid and BWP (Brake and Wheel Parts) s-cam shafts provide the highest quality to improve brake control, safety, efficiency, and operating profits. The S-cam shaft on the drum brake system is the mechanism used to transfer force from the air brake chamber to the brake shoes.
The air the brake chamber piston is attached to a push rod, which turns the slack adjuster. The slack adjuster connects the push rod to another the s-cam shaft, which then rotates. It is this rotation of the s-cam that pushes the brake shoes against the lining of the drum brake. There are several types of air brakes, including S-cam and wedge type brakes. The S-cam are the most widely used type in the heavy duty truck industry and therefore the style offered by us from Euclid and BWP (Brake and Wheel Parts).
