Dont really know Alex. The surface of the pad has dark areas on it and i cleaned them up with a bit of emery cloth and put them back on and the dark areas returned with in seconds of using the brakes along with the squeaking noise.

Maybe i should contact mintex and send them off to be looked at. The pad has also started hair line cracks in the center running from top to bottom.

p.s they never once faded around bedford, and at one point we did 16 laps without a cool down lap or a break to let the brakes cool off and they felt as good on the 1st lap as they did on the last lap of that run
