No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.When we use the brake disc, we can see that there are a few holes on it, so what is the function of this?
1. The scribing can make the dust on the brake disc due to friction with the brake pad dispersed into the air through the scribing groove as soon as possible, so as to avoid the rolling friction caused by dust and improve the friction between the brake disc and the brake pad.
2. Drilling is to improve the air flow speed and heat dissipation efficiency on the surface of the brake disc by cutting holes on the brake surface, so as to avoid heat accumulation and affect the braking effect, and also prevent too much heat from being transferred to the tire through the rim and reduce the risk of high temperature tire blowout.
3. When the perforated marking disc is driven in rainy days, due to the opening and grooving, it can effectively avoid the water film lubrication effect and prevent the braking effect from weakening. In sunny days, it can reduce the air film produced by the air, so as to improve the braking effect.
4. The brake disc through 500 degrees of high temperature ablation treatment, eliminate the internal stress, prevent the brake disc deformation and brake effect due to high temperature in the process of braking, but also rust resistance, corrosion resistance, prolong the service life.
