Some People Replace The Brake Pads Of Their Cars With Ceramic Ones. Why?
Aug 31, 2021
The types of brake pads we use are generally made of ceramic and semi-asbestos and semi-metal materials. Semi-metal and semi-asbestos brake pads are divided into two categories: low dust and high dust, European cars and American cars Cars generally use high-dust brake pad formula. High-dust formula brake pads have better braking effect and better friction coefficient. The disadvantage is that the service life is not long and the wheels are always black.
While Japanese and Korean cars generally use low-dust formula brake pads, this formula brake pads have better wear resistance, and the friction coefficient is slightly lower when the wheels are not blackened. In recent years, a new type of ceramic brake pad formula has been introduced. Its main advantages are long life, low noise, less dust, moderate friction coefficient, and good high temperature resistance.
The main structure of ceramic brake pads is basically the same as our commonly used brake pads. The main reason is that their friction materials are different. Compared with traditional brake pads, the big difference between ceramic brake pads is that they have no metal elements. Metal is the main friction material in traditional brake pads. It has a large braking force, but it wears a lot and is prone to noise.
The metal fiber metal content in traditional brake pads is relatively high, especially in cold, dry, and hot conditions, it is easy to cause sharp abnormal noises when braking, especially when we park at night to drive, the brake pads are more prone to abnormal noises
What are the advantages of ceramic brake pads?
1. Good mute effect: The material used in ceramic brake pads does not contain metal, and the mute effect is good, because the ceramic brake pads will not produce metal screams when they are frictionally braked with the brake disc.
2. Long service life: The service life of ceramic brake pads is 50% longer than that of traditional brakes. The service life of traditional brake discs can reach 60,000 kilometers, and the service life of ceramic actuators can reach 100,000 kilometers. In addition, ceramic brake pads will not leave any scratches on the brake disc even if they are worn.
3. High temperature resistance: When the vehicle is braking, the friction between the brake pads and the brake disc can generate a high temperature of 800~900℃. The ordinary brake pads will produce thermal degradation at high temperatures, which will cause the braking effect to decrease, while the ceramic The operating temperature of the brake pads is as high as 1000°C, and the ceramic brake pads can still maintain good braking effect at high temperatures and have good heat dissipation.
4. High friction coefficient: special materials and processing technology make the friction coefficient of ceramic discs higher than ordinary brake pads, and the braking effect is better than traditional brake pads.
Although ceramic brake pads are more expensive than ordinary brake pads, ceramic brake pads have a good braking effect, will not increase the wear of the brake disc, and have a long life. Therefore, ceramic brakes are still worth the money. This is also the main reason for some people to replace ceramic brake pads. reason.
