Car brake drums are typically made of cast iron, cast steel, or aluminum alloy and has a cylindrical shape. It is mounted on the wheel axle and generates braking force by rubbing against the brake shoes, thereby slowing down or stopping the vehicle. The brake drum is a traditional component in the brake system and forms a closed system with the brake shoes to prevent dust and dirt from entering.

The characteristics of brake drum include high thermal capacity and thermal stability, which enable it to dissipate heat quickly and prevent overheating during braking, thereby reducing the risk of brake fade. In addition, the brake drum can provide stable braking force to maintain vehicle stability and prevent loss of control.

The performance and advantages of brake drum are related to their material and manufacturing process. High-quality brake drums can provide better heat dissipation and longer service life, as well as reduce brake noise and vibration. High-quality brake drums usually have a flat surface to provide better braking performance and good balance to reduce vibration and noise.

The properties of brake drum include diameter, depth, weight, and material, which directly affect the performance and suitability of the brake drum. For example, a larger diameter and depth can provide better heat dissipation and stronger braking force, while a lightweight design can reduce the overall weight of the vehicle, thereby improving fuel efficiency.
