Help, in my 73 GTV I get an annoying break squeal when coming to a stop and I am releasing the pressure on the brakes. The fronts have been completely gone through with new rotors, pads, rebuilt calipers, and the rubber brake lines. I was hoping this would do the trick. It seems the softer I apply the brakes the louder the noise. Do not get any noise when applying the brakes hard. Anybody have any ideas as to what to look at next? Thanks.
