The mystery of a science science rotation of the iron plate brake disc

The brake disc is responsible for friction and deceleration in the entire brake system. However, compared to brake pads that are the same function, the brake disc is relatively simple in the modification direction, and it is also a component that is often ignored. However, in fact, a set of easy -to -use brake discs can not only strengthen the brake performance, but also reduce the chance of braking jitter, heat attenuation, and reducing disk surface deformation. Well, today we will come to popularize the mystery of the brake disc.

Car friends often consult my question, how to improve the brake performance with the lowest modification cost. In fact, my answer is often very simple. Let’s answer this question first.

In fact, the brake disc is the iron plate that the brake calipers clamped. This iron plate is also fixed on the wheel axis, and rotates synchronously with the hub. When the caliper clamp the brake disc, the brake disc can be decelerated, and then transmitted to the vehicle to the vehicle Specification, this is the basic working principle of the butterfly brake system. Therefore, the material of the brake disc is as important as the brake skin. If the temperature is not good, it will generate high temperature when driving fiercely, which will cause the brake disc In the case, the brake disc jitter occurs lightly, and the brake tray is cracking and affects safety. At this time, it must be replaced.

For our general daily street driving, if we want to improve the brake braking effect, the lowest cost operation is to choose a relatively high -quality high -performance brake pad. The general performance version of the brake pads is relatively good. If you want to go to the next level, you can consider the competitive version of the brake pads. The high temperature effect is absolutely excellent, but there is a problem with the competitive version of the brake pads. Without high, the brake foot feels average, and it is difficult to exert all the effects.

As for the brake disc, if it is not often drove on the track, it is recommended to choose some relatively soft products. In fact, the hardness of the original plate is relatively suitable. In principle, it is a soft plate with a hard piece. In fact, for the brake effect, the degree of fit will be better, and the braking effect can also be exerted to the limit. However, the disadvantage is that for a more soft brake disc, the wear will be more serious, the life span is also serious, and it may cause the brake disc deformation and cracking due to several emergency brakes, which need to be replaced directly.

Therefore, we often use some professional testing equipment to check the degree of wear and deformation of the disk, and then determine whether we can “save” the brake disc through grinding the brake disc, which is what we call the “light” disk. However, this operation cannot be performed again and again. The thickness of the “light” disk is worn by the thickness of the disk. Therefore, once the “light” is too large, the thickness of the disk will not work.

How to judge the matching of the disk and chip is reasonable? In fact, the method is also very simple, that is, by observing the color of the disk surface. After a period of time running in the plate, if the color of the disk surface is silver and bright, this basically indicates that the plate is well matched and the brake performance is good. However, if black, or the surface luster is dim, it means that the level of brake pads is not enough. You need to replace the brake pads with stronger friction coefficients to maximize performance. The reason is actually very simple, that is, the hardness of the brake pads is not enough. It cannot be worn normally with the brake disc surface. The braking force requires the clamping of calipers to obtain. This will cause the time to step on the brake pedal severely, the braking distance increases, and the surface of the brake disc surface will also appear higher. When the disk is cooled down, the iron will reduce the dark situation.

Therefore, in many cases, we will pay more attention to their own heat dissipation capabilities and enhance the heat dissipation capacity for the upgrade of the brake disc, which can naturally enhance the life expectancy of the brake disc and reduce the chance of annealing. We will choose a lot. The split brake disc (lighter heat dissipation is better), and the larger brake disc, that is, increased the disk (more use of the rear wheels), the hollow ventilation disk, holes and line disks. Regardless of that form, for the brake disc, it is actually to better heat dissipation. The brake discs with the same material, and the surface shape of various forms, in fact, the effect is the same in principle.

However, when we choose to modify the brake disc, we must also pay attention to the more reasonable brake disc design is actually more important. It is not more densely punching and more lines. The better heat dissipation effect also comes from the design of the vehicle’s intake pathway. Better cold and cooling heat dissipation is also very important for the cooling of the brake disc.

There are also problems that are worth mentioning and often ignored. Once you upgrade and modify larger caliper, thicker and larger brake discs, this will directly lead to a problem, that is, the increase in weight. This will increase the very precious “sub -spring quality”. In severe cases, it will directly lead to slower acceleration and increase fuel consumption, which will cause a certain negative impact on the suspension system. Therefore, when upgrading the brake system, the consideration of lightweight must also be increased. It is not bigger and better.

Therefore, in a more professional high -performance group, whether it is used or civilian, more choices are carbon pottery brakes. The brake discs produced by this material can use the weight of less than half to achieve the effect of the same size, and its high temperature resistance is far beyond the iron brake disc.

The so -called carbon ceramic brake disc, the ingredients are basically composed of carbon fiber, carbon, ceramics, etc. It is used with special supporting brake pads. Its high temperature resistance can reach more than 1,000 degrees Celsius, and the instant temperature resistance can reach more than 1200 degrees, and and more The heat dissipation performance of this material is better and the life span is longer. However, its disadvantage is that the working temperature must be between 300 and 800 degrees, so it is actually not suitable for the street cars where we travel daily. The main reason is that the price is very expensive.

Therefore, this carbon pottery brake disc is basically configured on some high -performance cars and professional racing. The highest -performance carbon ceramic brake system is configured on the top F1 car, which can ensure that it is stable in high temperature environments and stable. The support speed brakes, and no heat attenuation will occur, and it can also support the entire F1 game.

Therefore, for the brake system, whether it is a brake pad or a brake disc, it is a high -loss consumable. For the modification of our car, upgrading the brake system is naturally a must. However, how to choose the most suitable modification and upgrade parts, combine your actual driving needs and vehicle horsepower, the most reasonable matching and application of your own car is the most important.
