You also could have a zinc build up on the pads. Generally it wears off the rotors slowly during break in, but maybe that hard stop caused it to clump onto the pad and now there's a slight high spot.
If so then it should eventually burn off. Now this is just a guess on my part since there's no way the rotors warped from what you described.
If it doesn't go away give the guys at Baer a call, they are always helpful
