Ceramic brake pads

Ceramic brake pads subvert the concept of ceramic brakes in the traditional sense. Ceramic brake pads are composed of ceramic fiber, iron -free fillers, adhesives and a small amount of metal, including mineral fiber, aramid fiber and ceramic fiber ( Because the steel fiber is rusty, noise and dust are generated, it cannot meet the requirements of ceramic formulas), which is lighter and more expensive than other brake pads. Ceramic brake pads are cleaner and quiet, and while providing excellent brake performance, while providing excellent brake performance, while providing excellent brake performance, it is provided. Do not wear out. The ceramic formula does not refer to the formula of ceramic fiber. It is mainly based on the performance of the material whether a formula is a ceramic type. However, this material does not refer to any raw materials, but the performance of the finished product.

Advantages

Ceramic brake pads have the following advantages compared to other types of brake pads:

(1) The biggest difference between ceramic brake pads and traditional brake pads is that there is no metal Essence Metals in traditional brake pads are the main materials that produce friction. They have large braking force, but they have large wear and noise. After installing ceramic brake pads, it will not produce abnormally at the normal driving (that is, the sound of scraping). Because the ceramic brake pads do not contain metal ingredients, the traditional metal brake pads and the metal screaming of the traditional metal brake pads and dual puppets (that is, the brake pads and brake discs) are screaming.

(2) Stable friction coefficient. The friction coefficient is the most important performance indicator of any friction material, which is related to the good or bad brake film braking capacity. During the brakes, the heat caused by friction and the increase in working temperature. The friction material of the general brake pads was affected by the temperature, and the friction coefficient began to decrease. In actual applications, friction will be reduced, thereby reducing the braking effect. The friction material of ordinary brake pads is immature, and the friction coefficients are too high to cause unsafe factors such as out of control, burning slices, and scratching brake discs during the braking process. Even when the temperature of the brake disc is 650 degrees, the friction coefficient of ceramic brake pads is still around 0.45-0.55, which can ensure that the vehicle has good brake performance.

(3) Ceramics have good thermal stability and lower thermal conductivity, good wear resistance. The long -term use of temperature is 1000 degrees. This characteristic makes ceramics suitable for high -performance requirements for various high -performance braking materials, and can meet technical requirements such as high -speed, safety, and abrasion resistance of brake pads.

(4) Have good mechanical strength and physical properties. Can withstand large pressure and shear force. Before assembly and use, the friction material products need to be processed by drilling, assembly and other mechanical processing in order to make a brake pads assembly. Therefore, friction materials must be required to have sufficient mechanical strength to ensure that no damage and fragmentation occur during processing or use.

(5) It has very low thermal failure. Regardless of the first generation of ceramic products of M09 or the fourth-generation ceramic brake pads of TD58, even when the temperature of the brake disc reached 650 degrees, the friction coefficient of the ceramic brake pads is still 0.45-0.55 leftOn the right, it can still ensure that the vehicle has good braking performance to ensure safety. The heat attenuation of the brake pads is small.

(6) Improve the performance of the brake pads. Because of the fast heat dissipation of ceramic materials, its friction coefficients are higher than the friction coefficient of metal brake pads in the manufacturing of brakes.

(7) Safety. The brake pads will generate instantaneous high temperature during braking, especially when driving at high speed or emergency braking. In high temperature, the friction coefficient of the friction tablet will decrease, which is called heat recession. The heat decline of ordinary brake pads, the increase in the temperature of the brake oil during high temperature and emergency braking causes the brake braking to delay, and even the low safety factor of the brake effect.

(8) Comfort. In comfort indicators, the owner is often concerned about the noise of the brake pads. In fact, noise is also a problem that ordinary brake pads cannot be solved for a long time. The noise occurs in the non -normal friction between the friction tablet and the friction plate. The causes of the production are very complicated. The braking force, the brake disc temperature, the vehicle speed, and the climatic conditions may be the cause of noise.

In addition, the reasons that are produced by the three different stages of noise at the beginning of braking, braking implementation and braking release are different. If the noise audio is between 0 and 550Hz, the car will not feel it, but if more than 800Hz, the owner can obviously feel the braking noise.

(9) Excellent material characteristics. Large granules/brass/high -grade ceramics (non -asbestos) and semi -metallic materials such as ceramic brake pads have the advantages of high temperature resistance, abrasion resistance, brake stability, repairing brake discs, environmental protection, long noise life life, etc., overcome The defects of traditional brake pads are the most advanced ceramic brake pads in the world. In addition, the ceramic slag ball content is low, and the enhancement is good, which can also reduce the wear and noise of the brake pads.

(10) Long service life. The service life is the indicator that everyone is very concerned about. The service life of ordinary brake pads is less than 20,000 kilometers, and the service life of ceramic brake pads is more than 20,000 kilometers. That\'s because the unique formula used by ceramic brake pads is only 1 to 2 types of static powders, and other materials are materials without static electricity. It affects the aesthetics on the wheel. The life of ceramic materials is more than 50%compared to ordinary semi -metals. After using ceramic brake pads, no scratches (that is, scratches) on the brake disc, extending the use of 20%of the original car brake disc.
