I've been doing my own maintenance on all of my bmw's since I was 16 and i've never had to change rotors with brake pads.
How would one know that they aren't warped or aren't "too thin". I can get a micrometer/calipers to measure thickness but what determines too thin? How thick is a new rotor to spec (to gauge life)

I'm at 60k and was planning to do a full brake job myself. Brakes work really well now (other than dust) and if I don't need to pay ~$80 per wheel for new rotors, I'd be happy.
