Lost clutch pedal the other day tried to bleed no joy, just put new slave cylinder on & still no good,

when pedal is pressed down I can almost hold the bit inside the slave cylinder with my finger  :oops:

Any idea's


Thanks in advance

I had a similar problem last week with my sons Defender 300TDI, not sure if the symptoms are exactly the same but it may be worth checking. The clutch pedal went solid and failed to operate the clutch at all, after checking the usual things I removed the slave cylinder and could not feel the clutch fork, I decided the only thing to do was to remove the gearbox to see if I could find the problem. It soon became apparent what the problem was, the pivot ball had completely worn through the clutch fork, this then caused the piston in the slave cylinder to extend to its maximum which made the clutch pedal go solid.
I hope this is not the case with your Disco as it is much easier to remove the gearbox on a Defender than a Disco, by the time I repaired all the siezed bolts and screws and got it back together about 15 hours had passed!!!

Good luck

Put a clamp on the clutch flexi pipe and then try the pedal. If it still does it, then air in the system or the master cylinder needs attention.

Is the slave cylinder bleed screw above the inlet or below the inlet

Make sure its above the inlet.............because bleeding can be be problematic...

If not check your master then gearbox off for the pivit arm..

Very comon problem.........had one go with a clutch that had only been fitted 4months.........just waiting for the manufacture to get back to us.........some people weld a cover plate over the back of the arm to strenghten it.
