Ya, my tone rings are NON existent on my new rotors. When I had my new rotors, pads, and lines put on some months back, they called and told me my ABS was on, before they started. I said I knew and I was not concerned. When I picked it up, they asked if I wanted my old rotors and I said no. Sadly, I didnt realize until a few days later, that I had noticed my rings were still on the old rotors. If I thought about it, I should have had them at least give me those, but whatever. Not like the ABS failure was the rings anyways.
