How to choose brake disc?

Before the car owner buys the brake disc, the car owner should first check whether the brake disc conforms to itself, whether the integrity of the product package, the anti-fake mark and the package mark are consistent with the mark on the brake disc, and whether the product model is consistent with the content of the qualification certificate. The brake disc produced by the normal manufacturer, the package printing is relatively clear, with license number, implementation standards, and so on, and the box is qualified. The brake disc with reliable quality can guarantee its service life of 8-120,000km. If fake or inferior brake disc is used, the braking performance can be produced in a short time, but in the long term, the brake disc will be easily deformed due to the high temperature caused by friction, which will reduce the braking effect and ultimately affect the driving safety.
