I seriously doubt that, I broke them in the same way I break in all my pads, and as I said it was a problem stopping but it was the fact that they performed better once they had a little heat in them, which told me that the operating temp had not been reached for the pad, and break in procedures will not afffect that at all. I want a street pad the performs at its best as soon as the brake pedal is pushed, not after I use the brakes 2 or 3 times.
