Is it better to have a hole in the brake disc or a solid one?

As a kind of easily worn-out parts, automobile brake discs often involve replacement issues during our use. Common car brake discs are basically divided into two types: perforated brake discs and non-perforated brake discs. So many friends have questions about whether it is better to perforate or not to perforate?

Today’s brake discs are mainly divided into two types: physical brake discs and ventilated brake discs. The physical brake discs are often said to be non-porous< /span>brake disc, and the ventilated disc refers to the brake disc with holes. Physical brake disc: A solid brake disc is easier for us to understand. To put it bluntly, it is a solid metal disc used for braking. There is no special structure. Because it is a whole disc, it usually has better rigidity.

Ventilated brake discs: There are two types of ventilated brake discs, namely the scoring disc and the perforated disc. Generally speaking, the ventilated brake disc has many holes on the circumference leading to the center of the circle, which are called air ducts. The ventilating disc of this kind of air duct makes it easier for air to flow through the air duct during the driving process of the car, and the air is permeable. Stronger and more conducive to the heat dissipation of the brake disc.

Which brake disc is better

The above briefly describes the characteristics of the two perforated or unperforated brake discs. Which brake disc is better? In fact, the two different brake discs have their own advantages and disadvantages, but in general, the advantages of the ventilated discs will be more, let's take a detailed look at their respective advantages and disadvantages.

Unperforated brake disc: Unperforated brake disc is also a solid brake disc. This kind of brake disc is usually simple in structure and is a solid piece in the overall form The brake disc is therefore relatively simple to manufacture, and therefore the cost is relatively low. It is relatively cheap at the time of purchase, and the solid disc is stronger in structure, and has better rigidity and is not easy to break.

Ventilated brake discs: Because of the holes in the ventilated brake discs, first of all, it is relatively complicated in manufacturing, and the holes are bound to be a certain degree Reduce the rigidity of the entire disc, so the requirements for the use of materials will be more demanding, so the price is higher, and the cost of replacement will be higher. However, in use, the ventilated disc can improve the cooling performance of the brake disc, reduce its thermal attenuation, and provide better braking ability.
