One of the biggest causes of holes in disc brakes is that many times a vacuum builds up between the brake pad and the disc, which can cause the brake pad to stick to the disc.

This can cause the brake pads and discs to stick after sudden and urgent braking. This can also lead to accidents. But, the holes in the disc do not create a vacuum and the pads do not stick to the disc.

Another reason is that friction from braking causes the discs to overheat. In such cases, there is a risk of disc cracking. But because of the holes in it, air continues to escape and the temperature of the disc is maintained. Along with this, the brake pads also do not overheat.

These holes expel water that accumulates on the disc during braking in humid or rainy weather, so the pads do not slide off the disc and braking is correct. However, if the motorcycle is standing in water for a long time during the rainy season, the disc should be wiped with a clean cloth. Therefore, Mr
