Heavy duty truck brake drums：Cast Iron
The scientific name of the brake hub is the brake drum, which is the main component of the drum brake system. The friction between the inner surface of the brake drum and the brake pads during the braking function. The brake drum is a cast iron piece shaped like a tambourine, which is fixed to the tire and rotates at the same speed.

When braking, oil pressure is used to push the brake shoes to contact the inner edge of the brake drum, and the friction generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking. Generally speaking, the brake hub is like a metal drum or a small bucket that is placed on the hub, and the bottom of the bucket is rubbed against the hub of the car to stop it when braking.
The brake drum is an important component of the drum brake system. The inner surface of the brake drum of the drum brake is where the braking device generates a braking torque. With the same braking torque, the diameter of the brake drum of a drum brake device can be much smaller than that of a disc brake. Therefore, in order to obtain a powerful braking force, a large vehicle used for loading can only install a drum brake in a limited space of a rim. Drum brake systems are typically installed on the rear wheels of large vehicles.
