  • Product overview

At present, there are disc brakes, drum brakes, and air brakes on the brakes. Many older cars have front and rear drum brakes. Many cars nowadays have disc brakes at the front and rear. Because disc brakes have better heat dissipation than drum brakes, they are less prone to heat decay during high-speed braking, resulting in better high-speed braking performance. But when cold braking at low speeds, the braking effect is not as good as drum braking. The price is more expensive than drum brakes. So now many Chinese cars use full disc brakes, while ordinary cars use front disc and rear drum brakes. Trucks and buses that are relatively slow and require high braking power still use drum brakes.

The brake disc of the disc brake is a circular plate that also rotates when the car is moving. Brake calipers are used to clamp two brake discs to generate braking force. Its relatively rotating brake disc is fixed. When pressing the brake, it clamps the brake disc to slow down or stop.

Drum brakes are sealed and shaped like drums, and there are also many in China called brake pots. It rotates when driving. There are two curved or semi circular brake shoes fixed inside the drum brake. When applying the brake, the two brake shoes are stretched out under the action of the brake wheel cylinder, supporting the brake shoes and rubbing against the inner wall of the brake drum to slow down or stop.

Material requirements

The material of the brake disc adopts China's gray cast iron 250 standard, abbreviated as HT250, which is equivalent to the G3000 standard in the United States. The requirements for the three main elements of chemical composition are: C: 3.1 to 3.4 Si: 1.9 to 2.3 Mn: 0.6 to 0.9. Mechanical performance requirements: tensile strength> 21on/mm2, with a hardness requirement of 187-241.

Alternative name

In English, brake discs are usually represented by: BRAKE DISC or BRAKE ROTORS, and brake drums are represented by: BRAKE DRUM. In addition, brake discs are also known as brake discs or brake discs in southern China. Actually, it all refers to one thing.

Origin distribution

Brake discs are cast products. Due to climate factors, the north is too cold and the south is too hot, so most of the production bases for brake discs are located in the latitude areas of Shandong, Hebei, and Shanxi in China. Especially in Laizhou and Longkou, Shandong, the brake disc industry started early and there are many manufacturers.

The company's main products include: automotive parts, diesel engine parts, engineering machinery parts, air compressor parts, die-casting machine consumables, and brake systems. It is a casting manufacturer that provides high-quality spare parts for the mechanical manufacturing industry.
