The black dust that accumulates on your wheels is what remains of your pads, which is a natural part of this process. Excessive brake dust may not be a result of normal wear and tear, however.

Why is there black residue on my rims?

When your brake pads heat up, their metallic particles get a static charge as they wear off the surface of the pad.
