Belt sander would be my first choice, and a grinder would be my second. You don't need to remove a lot of material - just break the leading edge at about 45 degrees.
I have a 2000S and I replaced the rotors and pads, but after a couple of months I had a squeal from one wheel. So I ordered the anti-squeal from Pelican and gave the anti- squeal sims a good blast on both sides. Allowed it to set a couple of hours and I no longer have a squeal.
