I have just bought my daughter a 1l corsa and she is finding it almost impossible to drive because the clutch bites about 1/2 to 1 inch from the floor . I have tried adjusting it but can get it no better using the haynes manual . I can get the biting point about 4 inches from the floor but this leaves the clutch pedal about 3 inches higher than the brake. The clutch is not slipping at all , I am wondering could the cable have stretched , or possibly could it have had the wrong cable fitted , as a shorter cable would solve the problems ?

No it wouldn't. Only a new clutch will.

As you suspect, the cable is slack. There should be an adjusting rod near the gearbox. Set the pedal height to the measurement in Haynes first, then take up the cable slack until you have a very slight amount of pedal movement before you feel the resistance of the clutch.

Why? If the clutch was worn, the cable would be more taught, hence it would bite right at the top of the pedal travel. When the friction plate wears, the diaphragm pushes further to close the gap, so the spring center pivots out more and the release arm retreats further, hence a tighter release cable.
Problem is on the corsa there is only the adjustment at the clutch adjustment rod , this sets pedal height and biting point together :( Can't believe the clutch can be knackered as it doesn't slip and I would have expected the biting point to be right at the top rather than right at the bottom :( Has anyone else seen this sort of problem with a clutch before ? If so was it a whole new clutch required ?
Thanks
Hmm - you don't say whether you've followed any specific procedure, so I'll ask - have you?
From what I remember of my Cavalier, and from other cars I have done, there's usually some sort of procedure for checking the clutch free travel etc etc - and on some cars I have seen a stop, under the pedal, which can be adjusted. Plus of course is the carpet too think/badly fitted etc. thus stopping the pedal from going down?
Followed the procedure in the Haynes manual There is no adjustment at clutch pedal end unfortunately

I don't know the corsa, but if it has a cable operated clutch then there must be some form of adjustment. If there is no threaded rod arrangement at the end of the cable, then it must be a self-adjusting type. Have a close look under the pedals to see how it is connected. If the only adjustment method that works leaves you with a sky-high pedal, then I would suggest that you replace the cable. They're not usually very expensive.
Could it be that the brake pedal is too low, rather than the clutch pedal too high, if you see what I mean?

Where did you adjust it, then? If you are adjusting the cable length at the gearbox, then it's a simple matter of setting it as desired. With no pedal adjuster, both the pedal height and the biting point position will be determined by what length you adjust the cable to. Shortening the cable length will give you both a higher pedal and higher bite point - find a happy medium.
There is a threaded rod at clutch end on gearbox , but there is no way to get a happy medium between pedal height and biting point :( It either bites an inch from floor and with correct pedal height , or pedal height 2 inches above brake , but bites 3-4 inches from floor. Have tried every combination , I'm beginning to think there is something wrong with the clutch itself now :(
I agree.
Clutches don't necessarily slip to show they're knackered nowadays. The diaphragm spring in the cover, or pressure plate if you prefer, can become weakened, distorted, have the ends of the "tongues" which contact the bearing worn away to give various faults, including slipping.
I say again only a new clutch will fix it, and incidentally if you do the job yourself, compare the height of the contact face between the old and the new one. I've got an old pic somewhere, but can't post it 'cos I can't find it.
