Slotting on the brake disc, punching holes on the brake disc, through these gaps and grooves, increase the air circulation, improve the heat dissipation performance, and can quickly remove the dust generated by friction, improve the anti-heat decay performance of the brake pad, and make driving safer. So why are there not many holes in the brake discs now?
1. If the disc surface is punched, the overall strength of the brake disc will be reduced, which will affect the braking effect.
2. After punching, the friction area of the brake disc is reduced, and the friction force will be lost to a certain extent.
3. After punching, the heat conduction area on the surface of the plate is reduced.
4. After the brake disc is punched and used for a period of time, fine cracks will appear around the ventilation holes, and even deformation and vibration will occur.
In a word, there are some drawbacks in the drilling of the brake disc, so there are not many holes in the brake disc now. By changing the material of the brake disc, the need for the drilling of the brake disc can be solved, and the product still has a good braking effect.
