There are two main kinds of brake disc, one is a physical brake disc, in fact, is a five-hole brake disc, and there is a ventilation disc, this is a hole in the brake disc, so what are the differences between the two kinds of holes and no holes?

1. Holed brake disc. This ventilation brake disc because of the existence of holes, first of all in the manufacturing will be relatively complex, and the hole is bound to reduce the rigidity of the whole plate to a certain extent, so in the use of materials will be more demanding, so the price is higher, the cost of replacement will be higher. But in use, the ventilation disc can improve the cooling performance of the brake disc, reduce its thermal attenuation degree, and provide better braking ability.

2. Undrilled brake disc. This kind of solid brake disc is usually simple in structure. It is a solid brake disc in the overall form, so it is relatively simple in manufacture, so the cost is relatively low, and it is relatively cheap at the time of purchase. And the solid disc is more solid in structure, better rigidity and not easy to break.
