After investigating the rear wheels and their friction (which I think is due to the rear diff leaking) I went to move my car and when I took it out of gear the clutch had little resistance as it usually does. I went for a little drive and the bitpoint is at the very end of the clutch travel so my foot is to the floor, I change gear and as soon as I take the clutch up it engages jerkily.

Could this be that the cable has snapped?
Is it hydrolic and there is a lack of pressure somehow?

What is it likely to be? Any ideas welcome thanks,
