My clutch pedal went to the floor a while back. Bled it and it was ok..untill I booted it. So then I thought..master cylinder..tried that, no difference. So now it was starting to get soft again after driving like a granny for a couple of week..then it slipped a couple of times..bled it again..slipping like a nutter. Haha
Fitting a new clutch, flywheel and slave cylinder tomorrow so will tell you of my findings!!
Its a weird problem on mine though.
For you I would first check the bit of plastic from the master cylinder to the clutch pedal..probably snapped..usually do. Haha
Then you'll encounter a sod of a job

haha
