I have CTS-V 4 piston calipers with the hawks ceramic pads and slotted and driller rotors... These things have begin to squill something awful! On hot days its right away but on cool days once brake temp gets up. I can not get in touch with anyone at hawks that will help me out. Anyone have this problem or have a fix? The rotors themselves have very little wear and just a slight texture. I obviously cant have them turned but I am on the verge of just putting the high end GM pads back on and seeing if that fixes my problem.
