Ye it was righthand thread... and Oh shoot, I hope it hasn't got an electric motor, as thats the first Ive heard lol.
Straight after posting this I went back to it and the bloody thing turned didnt it, pretty easy as well because I could turn it with some bull nosed pliers. I tried them first and bent them initially lol.
So thats all sorted now. Second nightmare was getting the pins back in the caliper, OMG! I was using grips, hammer, lots of grease and Irwin clamp to get the bastards back through the rubber sock.
Now to top of a **** day Ive gone and snapped my locking wheel nut when putting the wheel back on, over tightening again. Thats going to be a challenge getting that off now!
