Brake discs are generally made of iron, and the working environment is harsh. If the vehicle is not used for a long time, it will gradually rust. This is normal, but to some extent, these rust marks will affect the normal operation of the brake system, so it is necessary to remove the rust on the brake discs in a timely manner. Next, we will bring you several methods to remove rust on brake discs.
If the rust is very light, there is no need to deal with it specifically, as the rusty areas of the vehicle will be worn off after multiple uses. But if the rust is severe, it can cause uneven surface of the brake disc. At this point, it is best to drive the car into the repair shop and polish the rust clean with sandpaper. After cleaning, check the surface of the brake pads for any abnormalities. After installation, conduct a road test and drive at a speed of 70km/h on a flat road surface. Apply multiple brakes to ensure that there are no abnormalities.
If the rust is too severe, the repair shop is also powerless. Therefore, if the vehicle is not used for a long time, the vehicle should be regularly maintained to avoid serious rust on the brake discs.
