Brake drums, the rotating components of drum brake systems, play a critical role in vehicle safety. When the brake pedal is pressed, brake shoes expand against the drum's inner surface, converting kinetic energy into heat through friction. The material composition, dimensions, design precision, and compatibility with brake shoes collectively determine the system's responsiveness, braking force, stability, and durability.
