right had a look today and its not hub faces a broken securing screw doh lol.

But i put the old discs and calipers and althou their shite and dont stop very well and there is still a slight judder its nothing like with the escos calipers so may be the discs after all (judder with them could be slight warping frmo the disc where it was juddering with the damaged hub before had), only way really i guess is try and get some other cossie discs to try on it and go from there.
