The S‑cam rotates to force the brake shoes against the drum, converting air pressure into stopping power. It is a direct replacement for worn, seized, or damaged camshafts on trailer axles equipped with 16.5‑inch brakes. Replacing the camshaft restores proper brake adjustment, even shoe contact, and reliable braking performance.
