Disc brake squeal is and has been a common complaint since the advent of disc brakes. It's annoying, but isn't really hurting a thing, and actually is (here comes the dreaded words) quite normal. The squeal you hear is actually a high frequency vibration between the pads and the caliper pistons. The best way to try to eliminate the squeal is to remove the pads and apply some anti-noise compound to the backside of the pads, clean the rotors, and clean or replace the pads. If that doesn't work then there's not much else that can be done short of replacing parts and crossing your fingers.

So far I haven't had the squeal if I apply the compound.
I also spray the caliper and pistons with brake cleaner and use a toothbrush to scrub all the crud off before installing the new pads.

This is a FWIW. My 12 UC has done that since it was new. Like others, I took it back, they "cleaned the rotor". For the first 50 miles, it was fine, then sounded like an old school bus when it stopped. At 11K, I took it in to my indy shop for a new rear tire, and while talking to the wrench, he had a suggestion. He said that while the rear wheel was off, that he'd file the leading edge of the brake pads. Just round them over a little bit. Did it fix it for good? I don't know, it's only been 200 miles. But the rear brake is silent now for the first time. I do have a set of Lyndal pads sitting on the shelf though. If it starts squeeling again, I'll put them on and see if THAT might fix it. It is frustrating.....a $20k+ bike sounding like an old beater coming to a stop.
