What are the precautions for replacing China brake shoe

First, when changing China brake shoe, you must pay attention to polishing its corners. Generally, a beveled surface is reserved for China brake shoe at the factory, commonly known as "chamfering". In addition to this "chamfer", the edge position of the entire friction surface needs to be polished. This process is actually noise matching.

Because the old China brake shoe and the brake disc have gone through tens of thousands of kilometers of "lingering", they have formed a certain styling complement to each other.

In other words, the old China brake shoe has carved a groove of its own on the brake disc. Although it is not easy to distinguish with the naked eye, there will be a certain amount of friction noise after the China brake shoe is replaced. Because it doesn't match, it's like wearing shoes that are one size smaller.

Therefore, by polishing the edges and corners, the new China brake shoe can be completely stuck into the brake disc groove left before, so that no noise will be generated, and the braking force will be sufficient.

Note for replacing China brake shoe: Do not brake with big feet

The second point is that after changing to China brake shoe, try not to brake with big feet, let alone slam the brakes. Because the friction surface of the new China brake shoe does not fit perfectly with the surface of the brake disc.

The size of this fitting area directly determines the effect of braking. Since the old China brake shoe left its own marks on the brake disc, it is uneven when viewed with a microscope, so the new China brake shoe needs to adapt to these marks first, and then the contact area will increase slowly.

There is a problem in physics, and I will tell you about it here. Many people believe that the larger the size of China brake shoe, that is to say, the greater the total friction area, the greater the braking force. This statement, according to the interpretation of middle school physics, is wrong. Because according to the formula F=uN, the friction force has nothing to do with the contact area.

So, why do high-performance cars choose large-size brake discs and China brake shoes? A more reasonable explanation is that the increase in the contact area is conducive to heat dissipation and reduces the thermal attenuation effect during braking. Moreover, if the China brake shoe is small, it is easy to be rubbed very thin, and if the China brake shoe is large, it will delay the time of thinning.
