The advantages and methods of determining the quality of ceramic brake pads
Ceramic brake pads are composed of ceramic fiber, iron-free filler material, adhesive and a small amount of metal. It has very good performance and is welcomed by consumers. The following are the advantages of ceramic brake pads and how to determine the quality of ceramic brake pads.
Advantages of ceramic brake pads
1. No abnormal noise, avoiding the sound of friction with the brake disc.
2. High temperature resistance: The high temperature resistance of ceramic brake pads is 650 degrees. (The high temperature resistance of brake pads of original vehicles is about 260 degrees). Particularly suitable for use on vehicles with mountain terrain.
3. Ceramic brake pads will not be scratched on the brake disc, extending the service life of the original car brake disc by 20%.
4. Fast heat dissipation. Ceramics have good thermal stability, low thermal conductivity, and good abrasion resistance. The long-term use temperature is 1000 degrees. This characteristic makes ceramics suitable for high-performance requirements of various high-performance brake materials, and can meet the technical requirements of high-speed, safe, high wear-resistant brake pads.
5. The friction coefficient of ceramic brake pads is higher than that of metal brake pads, and the friction coefficient is stable. 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.
How to determine the quality of ceramic brake pads
1. Look at the thickness: The thickness of a new brake pad is generally about 1.5cm, and it will gradually become thinner with constant friction during use. When the thickness of the brake pads is observed with the naked eye, the original thickness is about 1/3 (about 0.5 cm). Owners will increase the frequency of self-tests and are ready to replace them at any time. In some models, due to the design of the wheel hub, there is no condition for visual inspection, and the tires need to be removed to complete.
2. Brake warning light: Use the brake warning light on the dashboard as the basis for judging whether the brake pads should be changed. Some high-end cars only have brake warning lights and generally the brake warning line only has the front brake pads. When the warning light is on, if it is changed at this time, it is already quite dangerous. Because some of these warning systems directly sense the thickness of the brake pads, others cause the warning lights to turn on only after the brake pads have been completely worn and the brake fluid is extremely reduced. If it is the latter, wait until the warning light comes on, the brake pad metal base and the brake disc are already in the iron grinding state. At this time, you will see the bright iron cutting near the edge of the tire. Therefore, we recommend that you check the condition of the brake pads regularly.
The above is the introduction of the advantages of ceramic brake pads and the method of determining the quality of ceramic brake pads. I hope everyone will understand the advantages of ceramic brake pads and the method of determining the quality of ceramic brake pads, which will be helpful to everyone.
