Horrible Squeaking and Rattle

I just replaced my rotors and pads on my 2001 M3 with slotted Stoptech rotors and Hawk break pads and now I have horrible squeaking and rattling from the rear of the car. The squeaking may also be from the front as well but I cannot tell. I have done the bedding of the brakes but the squeaking is still there and very loud. When slowing down to a stop and releasing the brake it sounds like there is rubbing, but only at low speeds. Which makes me think there is possibly air in the brake lines? I have not flushed the brakes yet but will do so soon. Any thoughts? Obviously I'm a Nub so be kind please. lol

I don't use Hawk pads, but do use StopTech slotted rotors (+ SS lines and Motul RBF600) for the street and HIGHLY recommend the StopTech ST Street Performance pads for street use, they're my favorite out of the many I've tried.
They're not track pads, but they're more than capable of handling heavy Canyon carving, and actually are great for aautocrossdue to the phenomenal cold bite.
They're cheap too (and bed easier than anything else I can think of), so it's worth trying.

While flushing and bleeding your brakes is a good thing to do once a year anyway, it won't do anything for the squeal. Which Hawk brake pads did you get?
