Mike, gimme the keys on the next get together. I'll make sure they don't make noise, for you. It may include a few stops from 100-120 to near stopped, but we will get it taken care of.
On a side note, if you have a pressure washer, give the rotors a good spray down, to get any loose contaminants out of the holes of the rotors. That noise you're hearing is fine glazing that you're getting between the rotors and the pads. You're getting that perfect resonance, like you would get if you were sliding a piece of furniture across a wooden floor, or pulling a chair out, to sit on. Same Noise.
You need to take them out, and knock the stank off of them, a little. If they ever start making this noise, steel or CCBs, you're not hard enough on the brakes. You gotta get out of Miss Daisy mode, and get on them, a little.
