Sometimes the owner says that his car has abnormal noise when braking, but they are not very concerned. There is abnormal noise in the brakes, which may be caused by the hard spots on the brake pads rubbing against the brake discs. At this time, you should step on the brakes to see if the abnormal noise can be alleviated or disappeared. If you can slow down, you can continue to use it for a while. If you can’t, you must go to the 4S shop for inspection. Especially now, there is a lot of rain. In the case of humidity, the brake cylinder may not return to the position after braking, causing the brake pads and the brake disc to rub for a long time, thereby causing abnormal noise.

The new car coating is better than the sealing glaze. Some car owners don’t know much about the new car coating or sealing glaze. Here, it is recommended that the qualified car owners should paint the new car. Because the coating is to use a coating machine to spray the liquid wax with negative ions evenly onto the paint. Because the liquid wax has static electricity, it will be automatically adsorbed onto the paint, and then the low-rotation motor will be used with the sponge wheel to make it transparent. The filler is further extruded on the paint, so that the shelf life of the coating can reach 1 to 2 years, but the price is relatively high. The sealing glaze is to press the enamel on the surface of the lacquer by high-frequency vibration of the machine, so that the protective layer can achieve the purpose of protecting the lacquer surface. The shelf life is about 6 months, and the price will be relatively low.
