Brake disc knowledge

The brake disc, in simple terms, is a round disc that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop. Disc brakes are effective and easier to maintain than drum brakes.
The brakes have disc brakes, drum brakes and air brakes. Many older cars have front disc brakes and rear drums. Many cars have disc brakes front and rear. Because the heat dissipation of the disc brake is better than that of the drum brake, in the high-speed braking state, it is not easy to produce thermal recession, so its high-speed braking effect is good. But at low speed, the braking effect is not as good as that of drum brakes. The price is more expensive than the drum brake. Therefore, many middle and high-end cars use full disc brakes, while ordinary cars use front discs and rear drums, while relatively low-speed trucks and buses that require high braking force still use drum brakes.
The drum brake is sealed and shaped like a drum. There are also many called brake pots in China. It turns when driving. There are two arc or semicircle brake shoes fixed inside the drum brake. When you step on the brakes, the two brake shoes spread out under the action of the brake wheel cylinder, supporting the brake shoes to rub against the inner wall of the brake drum to slow down or stop.
Brake discs are divided into solid brake discs and ventilated discs according to their structure. The physical brake disc is a metal disc used for braking, and there is no special structure. Ventilation discs are divided into two forms, namely scribing discs and perforated discs. The functions of the two treatment methods are to improve the cooling performance of the brake disc, reduce its thermal attenuation, and provide better braking capability.
Brake discs are divided into carbon fiber ceramic brake discs and metal brake discs according to different materials. However, due to the excessively high manufacturing cost of carbon fiber ceramic brake discs and the poor braking force at low temperatures, although they have excellent thermal decay resistance, they are still Not used by most vehicles. In order to increase the resistance to thermal decay, some manufacturers also treat the metal brake discs with carbon fiber to improve their ability in this regard, and at the same time avoid the problem of poor low temperature performance of carbon fiber ceramic materials
Before replacing the brake disc, first check whether the replaced brake disc is a genuine accessory, whether the integrity of the product packaging, the anti-counterfeiting mark and the packaging mark are consistent with the mark on the brake disc, and whether the product model is consistent with the content of the certificate. The brake discs produced by regular manufacturers have clear packaging and printing, with license numbers, implementation standards, etc., and the packaging box has a certificate of conformity, production batch number, production date, etc. The use of reliable quality brake discs can guarantee its service life of 80,000-120,000 kilometers. If fake or inferior brake discs are used, braking efficiency can be produced in a short time, but long-term use, the brake discs are easily deformed due to the high temperature generated by friction, reducing the braking effect and ultimately affecting the driving safety.
