Have had a very enjoyable night in the freezing cold with rain p*****g down. I have been trying to replace my back disk brakes and pads. I opted for the ktr fast road discs which are fine. The brake pads i have chosen are FERODO DS2500. I have the pads all set up in the calliper and the disc has been put on but the two holes in the caliper which join it to the hub are not matching up with the holes in the hub. The piston has been wound correctly back. It appears that the brake pads are to thick. Is this correct is it possible or am i making another mistake. Any help appreciated, cheers.
