This process is noise matching.

This is because the old brake pad has been running for tens of thousands of kilometers. It has been running-in to form a complementary shape between it and the brake disc. However, if the new brake pad is replaced, friction will occur, so it needs to be run-in to make it The brake pad can be fully fitted so that it does not produce noise and can also make the braking force sufficient.

4. For the newly replaced brake pads, if you want to make it work, you need at least 500km to run in, and before that, you should properly control the speed of the car, and predict the road conditions when going on high speed to prevent sudden braking.
