If your brake discs are starting to show a lot of dents, they have reached their wear limit or they are bent, it's time to replace them. The wear limit can be found in your workshop manual, it is mentioned on some discs on the disc itself.
It is very wise to replace both sides at the same time, if you don't do so, there is a great risk of a difference in braking force between left and right, which can lead to dangerous situations.
All brake discs are supplied without bearings, retaining rings, mounting bolts, etc., please add them (if applicable, for your car, they will be indicated in the Options tab).
