    not with a torch wrench but just with accurate hand tightening :)

    There are instructions for uploading pics.

    Does a torch wrench light up when you get to the correct torque?

    PS - I'm not really sure what has broken?

    Overtightened? A lot.
    You will probably be fine with five bolts, but not repairable.

    It may have gone in misaligned for a reason or had a piece of debris in there, but either way it would have shown up in the torque to do it up.

    Definitely busted, and you may call me a wimp but I wouldn't trust it, considering how important brakes can be. At least before you ride it again get a torque wrench and check that the other five are OK.

    Email Hope they might be able to help. They will be used to seeing cracked hubs they see a lot of them because even though Hope hubs are so awesome and bullet proof and awesome and rad and gnarly they do seem to fall apart regulary.
