The S-cam converts the linear push of the brake chamber into rotational force to spread the brake shoes against the drum, slowing the vehicle. It is designed specifically for Hendrickson Intraax and HXS series trailer axles equipped with 16.5-inch Q-style drum brakes. You would replace this part when the camshaft is worn, seized, or after a brake overhaul to restore reliable, even braking performance.
