Uneven brake disc wear left-rear wheel

Savestones · 29th June 2022, 21:21

I recently changed my rear brake discs and pads, but after some time of driving I noticed some uneven wear on the brake disc on the left rear side:

Upon noticing this, I regreased the guide pins, caliper, saddle/brake pad carrier and the brake pads and refitted everything, hoping that smooth movement would even out the pads and make my brake disc nice and shiny again.

Unfortunately, this did not seem to work fully. Now, the innermost ring of rust-free brake disc you can see in the picture has expanded somewhat, but the majority of the rust is still there (will make a picture in the morning). Does this mean I waited to long and have to spring for new brake discs? Or can I still work some angle grinder magic (which was also done on my front brake disc) and continue with these - rather new - brake discs?
