Brake drums

1. It has the function of automatic braking, so that the brake system can use lower oil pressure, or use a brake drum with a much smaller diameter than the brake disc.
2. The parking brake mechanism is easy to install. Some models with disc brakes on the rear wheels will install a drum brake hand brake mechanism in the center of the brake disc.
3. The processing and composition of the parts are relatively simple, and the manufacturing cost is relatively low.

*High strength and hardness of braking
*Wear resistance, tuns the convex surface smooth
*Heat tendons, scattered potential performance is better
