Characteristics of Ceramic Brake Pads

Characteristics of Ceramic Brake Pads

Ceramic brake pads are a type of brake pad that includes mineral fiber, aramid fiber and ceramic fiber. Many consumers will initially mistake ceramic as being made of ceramic, but in fact, ceramic brake pads are made from the principle of metal ceramics rather than non-metal ceramics. At this high temperature, the surface of the brake pad will be sintered metal-ceramic similar reaction, so that the brake pad has good stability at this temperature. Traditional brake pads do not produce sintering reactions at this temperature, and the sharp increase in surface temperature can cause the surface material to melt or even produce a cushion of air, which can cause a sharp decrease in brake performance after continuous braking or a total loss of braking.

Ceramic brake pads have the following advantages:

1. Ceramic brake pads do not contain metal components, the screeching sound of traditional metal brake pads rubbing against each other (i.e. brake pads and brake discs) is avoided.

2. Stable friction coefficient. Friction coefficient is the most important performance indicator of any friction material, which is related to the good or bad braking ability of brake pads.The friction material of ordinary brake pads is not mature, and the friction coefficient is too high causing unsafe factors such as loss of direction during braking, burned pads and scratched brake discs. Even when the temperature of the brake disc is as high as 650 degrees, the friction coefficient of ceramic brake pads is still around 0.45-0.55, which can ensure that the vehicle has good braking performance.

3. Ceramic has better thermal stability and lower thermal conductivity, and good wear resistance. 

4. It has good mechanical strength and physical properties. Can withstand large pressure and shear force.

5. Have a very low thermal decay property.

6. Enhance the performance of brake pads. Because of the fast heat dissipation of ceramic materials, it is used in the manufacture of brakes, and its coefficient of friction is higher than that of metal brake pads.

7. Safety. Ordinary brake pads thermal degradation of low, high temperature and emergency braking when the brake fluid temperature increases so that the brake braking delay, or even the loss of braking effect safety factor is low.

8.  Comfort. Among the comfort indicators, owners are often most concerned about the noise of the brake pads, in fact, noise is also a long-standing problem that cannot be solved by ordinary brake pads. 

9. Excellent material characteristics. Ceramic brake pads use large particles of graphite/brass/advanced ceramic (non-asbestos) and semi-metal and other high-tech materials with high temperature resistance, wear resistance, brake stability, repair injury brake disc, environmental protection, no noise long service life and other advantages.

10. Long service life. Service life is an indicator of great concern. The service life of ordinary brake pads is below 60,000 km, while the service life of ceramic brake pads is above 100,000 km. The life span of ceramic materials is more than 50% higher than that of ordinary semi-metal ones. After using ceramic brake pads, there will be no scraping grooves (i.e. scratches) on the brake discs, extending the service life of the original discs by 20%.
