hi, in the middle of chnaging the rear discs/pads on my ph2 172. bought a set of yozza discs with abs rings etc all fitted, got to the stage where i'm putting the new disc on and bolt carrier for pads back to caliper but it seems like the carrier wont go far enough over to line up with the holes in the caliper. like the disc isnt on far enough, pictures below show it. but its on as far as i can get it and nut is fully tight onto the hub. help!!! i'm confused.
