Although I have tried to ignore it, my StopTech brakes have never worked properly. Pedal force is high. I've been told to change the pads, to a softer compound, I guess. When brakes are applied they vibrate. Harry from Ztuner is of the opinion that there is some warpage on the blades and that a slight cut will correct the problem. The factory insists vibration is due to improper "bedding" of the pad/rotor surfaces.
