What are ceramic brake pads made of? (Down)
(5) Ceramic brake pads have a stable coefficient of friction. The coefficient of friction is the most important performance index of any friction material, which is related to the braking ability of the brake pad. During the braking process, due to the heat generated by friction and the increase of the working temperature, the friction material of the general brake pad is affected by the temperature, and the friction coefficient begins to decrease. In practical applications, the friction force will be reduced, thereby reducing the braking effect. The friction material of ordinary brake pads is immature, and the friction coefficient is too high, resulting in unsafe factors such as loss of direction control, burning pads, and scratching the brake disc during braking. Even when the temperature of the brake disc is as high as 650 degrees, the friction coefficient of the ceramic brake pad is still about 0.45-0.55, which can ensure that the vehicle has good braking performance.
(6) Ceramic brake pads have good thermal stability, low thermal conductivity, and good wear resistance. The long-term use temperature is 1000 degrees. This feature makes ceramics suitable for the high-performance requirements of various high-performance braking materials, and can meet the technical requirements of high-speed brake pads, safety, and high wear resistance.
(7) It has good mechanical strength and physical properties. Can withstand greater pressure and shear force. Before assembly and use of friction material products, mechanical processing such as drilling and assembly is required to make brake pad assemblies. Therefore, it is required that the friction material must have sufficient mechanical strength to ensure that no damage or fragmentation occurs during processing or use.
(8) Has very low thermal attenuation. Regardless of the first-generation ceramic products of M09 material or the fourth-generation ceramic brake pads of TD58, they can still ensure that the vehicle has good braking performance to ensure safety, and the phenomenon of thermal attenuation of the brake pads is very small.
(9) Comfort. Among the comfort indicators, car owners are often most concerned about the noise of brake pads. In fact, noise is also a problem that ordinary brake pads cannot solve for a long time. Noise is generated from the abnormal friction between the friction plate and the friction disc. The reasons for the noise are very complicated. The braking force, the temperature of the brake disc, the speed of the vehicle and the weather conditions may all be the cause of the noise.
In addition, the causes of noise are different in the three different stages of braking initiation, braking implementation and braking release. If the noise frequency is between 0 and 550Hz, the car will not feel it, but if it exceeds 800Hz, the owner can clearly feel the braking noise.

(10) Long service life. Service life is an indicator that everyone is very concerned about. The service life of ordinary brake pads is less than 60,000 kilometers, while the service life of ceramic brake pads is more than 100,000 kilometers. That's because the unique formula materials used in ceramic brake pads only have 1 or 2 kinds of powder containing static electricity, and the other materials are all non-static materials, so that the powder will be taken away by the wind with the movement of the vehicle and will not stick It affects the appearance on the wheel hub. The life of ceramic materials is more than 50% higher than that of ordinary semi-metals. After using ceramic brake pads, there will be no scratches (scratches) on the brake disc, which prolongs the service life of the original brake disc by 20%.
