The brake disc of the car is undoubtedly very important to the car, and the brakes we usually drive on depend on the brake disc to play a role, which assumes the role of deceleration and parking, and maintains the safety of the car. Although the brake disc is so important, there are still quite a few car owners who still have a vague concept of the brake disc, and today Xiaobian will explain the things about the brake disc at one time.
First, the working principle
The working principle of the brake disc is not very complicated, the brake disc, the sub-pump, the brake caliper, the tubing and other parts cooperate with each other and work through the control of hydraulics. The brake discs on the wheels follow the wheels, the sub-pumps are fixed to the base plate, the brake calipers are on both sides of the brake discs, and the hydraulic push friction pads and brake discs rub to generate braking force. Many brake discs are also designed with small holes for heat dissipation, which is a ventilated disc brake, which can help improve braking efficiency by dissipating heat in time. At the heat dissipation level, large brake discs are more effective at dissipating heat than small sizes.
Second, the brake disc is faulty
If you notice brake shake while driving, don't panic too much at first, the reason you need to think about the failure is that the brake disc may have been deformed. Deformation is due to the rapid wear of the brake disc or the entry of other foreign objects, which will make the surface of the brake disc not flat enough, which will cause the problem of shaking when braking.
If you continue to use the deformed brake discs, it will seriously affect the braking performance of the car, in addition to increasing the braking distance of the car, it will also lead to problems such as vehicle deviation, inability to steer, brake failure, etc., so once the problem is found, the replacement of the brake disc should be dealt with immediately.
3. Regular replacement
In the process of using the car, the wear of the brake disc itself is an unavoidable thing, so it is recommended that everyone usually go to the 4S shop to pay attention to check whether the brake disc needs to be replaced. Specifically, it should be noted that the thickness of the brake disc is measured regularly, and the wear of the front and rear brake discs is not the same, and it is necessary to replace it regularly according to the actual wear situation and the advice of professionals.
Fourth, the brake disc selection
As we all know, the "water" of the auto repair industry is very deep, and it is easy to be fooled into choosing products with low cost performance and no practicality without paying attention. Therefore, it is recommended that each brand of model is best to choose the original brake disc of its own model, and the original accessories of the exclusive model are more suitable for the car itself. Guaranteed professional brake discs have the characteristics of high structural strength, low tear, low wear, special paint and other characteristics, which can improve braking performance, timely response and precise control of braking distance.
