last night i drove around the city in stop and go stuff for a few hours,and i broke in my pads as the tec. that did my install told me very easy at first he also told me if i do major braking right away it scores the pads and they will make a lot of noise and not work well and after about 20 Miles or so the noise went away so i drove for about 40 more city miles and no noise so my tec. does know what hes talking about and then this am i drove some more city stop and go and the brakes work very well 10times better than stock and i'm not getting any noise....i'm very happy now....
