The brake disc is actually the "heart" of a car. It is the brake pads that transmit the vibration generated during the driving of the car to the brake disc, so it plays an important role in the brake system. Brake disc is the most important component of vehicle brake system. The brake pad can ensure that the brake oil flows on the brake pad to ensure the braking effect. If there is a problem with the brake disc, it will affect the brake performance and the normal use of the brake pads.

1. The brake disc is mainly composed of brake disc, brake fluid, brake oil and friction lining.

The brake system is composed of brake disc, brake fluid and friction plate, which are closely matched to form a vacuum braking force and make the brake system work in a vacuum state. The structure of the brake disc is very simple. Before installation, just inject the brake fluid into the brake disc and form a vacuum film on its surface. When braking at high speed, the brake fluid will quickly bond the surface of the brake disc and the brake pad together to form a large braking torque so that the brake device can work at the highest torque.

2. The brake disc is made of steel plate with higher hardness, which has poor wear resistance.

The brake oil is also widely used in the brake system, which is mainly used to prevent sparks caused by friction between brake discs. During braking, heat will be generated due to friction of brake oil. If the brake oil temperature is too high, the friction of the disc surface will increase, which will lead to the extension of the braking distance, and even the brake disc will burst. Therefore, the brake oil temperature shall not be too high.

3. The brake disc is made by friction of the automobile walking device (ABS), so the automobile brake system must be replaced regularly.

The brake system needs constant friction during operation. The brake components such as brake oil and brake caliper are working. The metal fragments on the friction material surface will wear the brake discs. Long term wear will cause excessive mineral composition in brake oil, resulting in sediment. The impurities in the brake oil will produce sludge). The brake oil is stuck on the brake disc, which will cause wear of the brake disc during use. Therefore, the brake disc will slowly wear out to a certain age before it needs to be replaced. It should be noted that you must go to the 4S store to replace the brake pad, because this will not only ensure the quality of the brake fluid, but also ensure that the brake pads will not wear to the brake disc during use, so as to ensure the brake performance. For some models that need to be used frequently, it is recommended that the brake pads should be serviced and replaced every 30000 km. Because the brake pedal will get stuck when the brake pads are not replaced for a long time.

4. In order to make the brake disc not produce too much friction resistance and achieve the best braking effect, the brake disc must have a small round hole (there will be a small round hole on the brake disc) to transfer the braking force in the braking system to the drum brake (ABS).

The small round hole is located between the brake disc and the brake pad, and the clearance between the brake disc and the brake drum is about 0.5~1.0 mm. This kind of small hole can not completely cover the brake disc when it is used for braking to avoid excessive wear of the brake disc due to too long braking distance. If the small hole on the brake disc is too small to completely cover and affect the friction effect of the brake disc, high temperature steam generated in the brake wheel cylinder will scorch the surface of the brake disc, causing a fire. Since this hole is usually not on the brake disc surface, it has no effect on the brake disc structure. In addition, the small round hole on the brake disc is in a closed state due to the high-pressure effect of the brake system. This small hole can neither be sealed nor damaged by people or animals, so it needs to be sealed to ensure heat dissipation.

5. There are more friction particles on the brake disc (between the brake pad and the disc surface). Constant friction on the brake disc surface will make the brake disc surface more polished.

If the brake disc is used for a long time, these friction particles will affect the heat dissipation between the brake pads, leading to the decline of brake performance. The brake pads generate heat continuously while radiating heat. The brake pads will also absorb more heat when they are heated, resulting in excessive brake disc temperature. The surface of the brake disc is too dirty, and the brake pads will continuously generate heat when the vehicle brakes.
