What is the brake disc replacement standard
The replacement standard of the brake disc is mainly determined according to the thickness of the brake pad and the wear of the brake disc, and also according to the kilometers traveled by the vehicle. The brake disc has a wear limit mark. When the wear mark disappears, it indicates that the brake disc should be replaced.
The brake disc plays a direct braking role by clamping the brake disc with the brake leather in the automobile deceleration braking. The material of the brake disc is generally cast iron, which is hard and wear-resistant, so it is used in the vital braking system.
Visually check whether there are deep grooves over 1.5mm on the surface of the brake disc. It is estimated that the brake disc needs to be replaced. Due to the different standards of each vehicle, it is generally 40000-60000 km. Pay attention to regular inspection. The brake disc normally uses about 100000 km, and the wear limit is 2mm. You can refer to these data for judgment.
When braking, there is a sharp sound, and the braking effect is poor, and it can not be improved after replacing the brake pad. At this time, the brake disc should be deformed due to long-time braking or frequent braking on long and small slopes after high temperature, the surface is burning and stubborn, and the hardness becomes larger. At this time, the honing method can be adopted, but the honing on both sides shall not exceed 3mm, otherwise the brake disc shall be replaced.
The brake disc is made of gray cast iron 250 standard in China, abbreviated as HT250, which is equivalent to American G3000 standard. The requirements for the three main elements of chemical composition are: C: 3.1 ∽ 3.4, Si: 1.9 ∽ 2.3, Mn: 0.6 ∽ 0.9. Mechanical property requirements: tensile strength > = 206mpa, flexural strength > = 1000MPa, deflection > = 5.1mm, hardness requirements: 187 ∽ 241hbs.
In English, the brake disc is usually represented by brake disc or brake rotors, and the brake drum is represented by brake drum. In addition, in the south of China, brake discs are also called brake discs and brake discs. In fact, they all refer to one thing.
There are two most common brake forms on the market: disc brake and drum brake. At present, most models have used disc brakes. Disc brakes have become the first choice for almost all cars with the advantages of small space, fast heat dissipation and light weight; Although drum brake does not have the above advantages, it has the characteristics of stable overall performance, strong braking force, low cost and easy maintenance, which makes it the best choice for buses and trucks. In addition, the adjustment of anti lock system ABS will also have a certain impact on the vehicle braking force distance. If the ABS adjustment is too sensitive and the tire grip has not fully reached the limit state, the ABS is already restraining the braking force of the brake, which will also lead to longer braking distance.
