Panic over, it was MOT place trying to get work out of me, fronts have half of pads left, rear is 1/3 left on one side almost full on other, caliper rebuilt coming...Bastards failed MOT and said I cannot ride the bike away because there's no brakes. Agreed I can come with pads and tools and change them myself. Guess who got proper bollocking and will never be used for anything again. What were they thinking? Put the old pads back and got free retest on the spot.
BTW, pads are not EBC and not sintered.
