What are ceramic brake pads made of?
Ceramic brake pads subvert the concept of ceramic brake pads in the traditional sense. Ceramic brake pads are composed of ceramic fibers, iron-free filler substances, adhesives and a small amount of metal.
Ceramic brake pads are a kind of brake pads. Many consumers mistakenly think that they are made of ceramics at first. In fact, ceramic brake pads start from the principle of metal ceramics instead of non-metallic ceramics. The high temperature generated on the surface can reach 800-900 degrees according to the measurement, and some are even higher. At this high temperature, a reaction similar to cermet sintering will occur on the surface of the brake pad, which makes the brake pad have good stability at this temperature. However, traditional brake pads will not produce sintering reaction at this temperature. Because the surface temperature rises sharply, the surface material will melt and even produce air cushions, which will cause the braking performance to decrease sharply or the brakes will be completely lost after continuous braking.
Features of ceramic brake pads:
Less dust on the wheel; long life of disc and dual; no noise/vibration/damage to disc. The specific performance is:
(1) The biggest difference between ceramic brake pads and traditional brake pads is that there is no metal. Metal in traditional brake pads is the main material that generates friction, which has high braking force, but wears a lot and is prone to noise. After installing ceramic brake pads, there will be no abnormal clamor (that is, scratching sound) during normal driving. Because the ceramic brake pad does not contain metal components, it avoids the metal clamor of traditional metal brake pads and brake discs rubbing against each other.
Ceramic brake pads have excellent material properties. The high-tech materials such as large-grain graphite/brass/advanced ceramic (non-asbestos) and semi-metal used in ceramic brake pads have the advantages of high temperature resistance, wear resistance, stable braking, repair of damaged brake discs, environmental protection, and long service life without noise. Overcoming the material and craft defects of traditional brake pads, it is currently the most advanced high-grade ceramic brake pad in the world. In addition, the content of ceramic slag balls is low and the reinforcement is good, which can also reduce the dual wear and noise of the brake pads.
Improve the performance of brake pads. Because of the fast heat dissipation of ceramic materials, when used in the manufacture of brakes, its friction coefficient is higher than that of metal brake pads.
safety. The brake pads will generate instantaneous high temperature when braking, especially when driving at high speed or emergency braking. At high temperature, the coefficient of friction of the friction plate will decrease, which is called thermal recession. Ordinary brake pads have low thermal decay, and the temperature of the brake oil in high temperature conditions and emergency braking will cause the brakes to delay braking, or even lose the braking effect, and the safety factor is low.
