[barmiebrumie]

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

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.

All done  :D ,



Had to replace the master cylinder & damper, had a real probelm bleeding though ended up ' drip bleeding' in the end (open bleed nipple & keep topping up for about an hour),

I had replaced the gear & transfer box's about 3 months ago, (R380 gearbox & 1.41 transfer box) while that was being done I welded a bar on the fork,


Thanks for all the advice

i have just replaced my clutch and just put the box back up problem now is ever time i press the pedel it stays on the floor and i have to reach down and lift it back up by hand but it was working fine till the clutch went

On a 300TDi Disco the clutch pedal 'goes over' if there is air in the system, so when you are bleeding it you have to press down and pull up. Once the air is gone the pedal doesn't travel far enough to do this.

A little tip i have found useful when bleeding discovery clutches.

Jack the front up by about a foot. Helps the air to get out (going uphill). :)

Good tip I have the same problem,

Try filling a wesco oil can with brake fluid, attach to the bleed nipple with a length of screen washer pipe,slacken the nipple  and pump away.
When the master cylinder reservoir is filled, you should have an air free clutch!
Or try the gunson easy bleed!
