I would start by checking to make sure everything is tight and lubed where lube is needed. Another thing you can do is an anti-squeal compound. I always called it Brake Quiet, the bottle I have is from NAPA years ago and is orange. With this said I hate to say that every time I put on high performance brake pads they squeal, doesn't seem to matter what brand, Hawk, EBC, even the carbon ceramic ones.
