The material of the front brake disc is steel, and the brake disc of this material is used because of its good wear resistance and mechanical strength, as well as low braking noise.

The front brake disc is a metal disc made of alloy steel and fixed to the wheel, which rotates with the wheel. When the vehicle is on the brakes, the brake caliper clamps the brake disc and uses the frictional force to slow down or stop.

The thickness of the brake disc is divided into front and rear. In general, the thickness of the front brake disc is about 32 mm, and the thickness of the rear brake disc is about 28 mm.

Brake discs are an important part of the braking system. If the braking system is to always slow down the vehicle safely and comfortably - bringing it to a complete stop if necessary - the brake discs must combine with the brake pads to generate braking torque (braking force).

A disc brake is a type of brake that uses calipers to squeeze pairs of pads onto a disc or "rotor" to create friction. This action slows the rotation of an axle, such as an axle, to reduce its speed of rotation or to keep it stationary.
