That rules out the wheel bearings. Is it coming from both sides? If it only happens when you hit the brakes, I agree its likely a brake issue. You can rule out the pads since the noise was present with both the old and new set. I'd take some 120 grit and do a little 'wax on, wax off' motion around the rotors to see what that does for you. How worn are the rotors? (ie, have they been turned several times)
