Thanks for your comments, sorry I didn't reply, been nowhere near the computer for quite a few days!
One of the problems is I don't have the build manual, bought second hand, manual was promised to follow etc etc. That torque is huge, how on earth do you get 180 or 250 accurately?? or do you just tighten till you get a hernia?
I'm buying the bits from CC on sat, so I'll also see what else they say.
Thanks again, Steve, I may take you up on the socket, I have bleed stuff, unless I can locate one closer to home.
Cheers
