How to do rust on the brake disc?

    Brake disc rust is normal. Brake discs are metal and are protected from direct exposure to air, resulting in oxidation and rust. What about that rusty? The little editor has brought two solutions to everyone:

    1. slight rust marks: the car will be ready for several times and the rust will wear away.

    2. serious rust marks will cause uneven surface of the brake disc. At this point, it will be very difficult to remove rust, even if it is "polishing", it will cause abnormal wear of brake pads, and there will still be jitter. It is better to drive the vehicle into the repair plant, remove the brake disc, grind the rust out with sand paper, check the surface of the brake pad or not, and make the road test after the installation is appropriate.
