Another idea is that the grinder WILL spin the rotor to some degree.. that might work to your benefit.


I'm quite sure that some of that lip is comprised of iron oxide... aka rust. You'll get through that.

I am actually shocked to read that so many others just put the new pads and wait for them to wear in.... you're only working with 5% - 10% of the working brake surface on those lips... scary!!

And isn't it quite possible that you could crack the pad material in half despite the metal backing?
