I have the same problem with my 1997 defender the clutch was slipping so I had it replaced an it was ok to start with biting at the bottom of the travel gradually it came up now its at the top and starting to slip again when towing is this the same fault can anyone help
I'd go to the introduction section or you'll get a hard time.
I would suggest the hydraulic system could be holding the clutch in the disengaged position slightly - or your thrust bearing is shot - see my reply from years ago!
If you think about it, the master pushes fluid along the line to the slave, the slave piston pushes the push-rod, this pivots the clutch fork which acts on the release bearing which in turn pushes in the fingers on the clutch cover diaphragm spring and releases the clutch plate from the cover/flywheel clamping forces to allow it to rotate independently from the engine. IF any of that system is not adjusted correctly it is very possible that the clutch is essentially being held off slightly.
I forgot the cover note on the picture - it's the bit that sits over the plate for those who don't know.
As the clutch plate wears the clutch cover must allow for this by slightly moving in on the plate to keep it clamped tightly between the clutch cover clamping face and the flywheel.
As this happens the fingers on the diaphragm spring will start to move out a little towards the release bearing this is now multiplied due to leverage, so a small amount of clutch wear can manifest itself as several mm on the spring fingers. So if you you have no slack in the system then as the clutch wears the release bearing cannot move back so the pressure on the cover increases which starts to release the cover from the plate.
Now you have a brand new plate and hydraulic components so the cover clamping plate should be right out against lots of new friction material, which means the spring fingers should be in quite far, but if your mechanic footered with the push rods and adjustment at the pedal etc it is possible it's been adjusted so much that the system is holding the clutch off.
The hydraulic system is notorious for being a pig to bleed and often it just takes a couple of days and driving to get it to feel normal, if the mechanic tried to adjust out what in fact was air in the system he may have got it quite wrong.
Check that there is some slack on the system while the clutch is sitting at rest for starters.
