Auto Front Rear Brake Drums：steel
The brake drum is a friction coupling of a drum brake. In addition to the strength and stiffness required as a component, the brake drum should have as high and stable a friction coefficient as possible, as well as appropriate abrasion resistance, heat resistance, and heat dissipation. And heat capacity.
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.
Mill-balanced for proper rotor function, no extra weights are needed
Drums are inspected for balance; resulting in smooth brake operation and noise reduction
Quality validated for proper metallurgy and correct brake plate thickness
Non-directional brake surface finish for consistent braking
A brake is a component of a braking system that generates a braking force that obstructs the movement of a vehicle or the tendency of a movement. Except for various retarding devices, automobile brakes are almost all friction brakes that use the friction between the fixed element and the working surface of the rotating element to generate a braking torque.
Integral casting The brake drum is integrally cast from high-strength gray cast iron or alloy cast iron containing Cr. This brake drum has a simple structure, convenient processing, and large heat capacity, but has a large mass, and is mostly used for medium and heavy vehicles.
Combination of steel plate and cast iron The brake drum is composed of a steel plate stamped drum plate and a cast iron drum ring, which has a small mass and is mostly used for cars and light cars.
Combination of light alloy and cast iron The main body of the brake drum is a light alloy material (such as aluminum alloy), which is lined with a cast iron ring. This kind of brake drum is not only small in weight, but also good in heat dissipation, and is mostly used in cars.
