Since the brake pads of new cars are relatively hard, abnormal noises will be produced when the brake pads collide with the brake discs. This is a relatively common phenomenon. In addition, new cars may have abnormal noises due to metal particles or foreign objects on the brake cylinder.

There are many reasons for the abnormal noise of the car brakes. One is that the abnormal noise will appear during the running-in period of the new car. In this case, the car will disappear after driving a few hundred kilometers. The second is that there is a problem with the assembly of the brake pads. It may be that the brake pads are installed upside down and only need to be reassembled. The third is that the brake cylinder does not return to its position, and the inside of the brake duct is rusted. It only needs to be polished with fine sand and then coated with lubricating oil. The fourth is that the brake pads are too worn, causing the alarm pads inside the brake pads to make a sharp sound, so the brake pads must be replaced in time to avoid scratching the disc and causing brake failure.
