Good morning All,
Again as always not been about for a while due to parental duties so apologies i hope everyone is well!
My question is this, i started my landy up for the first time since the snow which is a rather longer time than i would have normally left her and the clutch pedal was not not working it was just stuck, i have managed to free it and driven her but is this just a sticky linkage? as the clutch now bites a little lower than before i think.
Any ideas/ help/ advice would be very much appreciated.
Thanks Andrew.

Check the pedal pivot point. Under the bonnet remove the screws holding the pedal to master cylinder linkage cover and check there first of all. Easier than the hydraulics. The pedal pivot bearings wear and they never get lubricated.

Afternoon Andrew.
The screws retaining the cover can be difficult sometimes but otherwise it shouldn't take long. Get someone to operate the clutch pedal when the cover is off while you watch the movement.
It will be worth spraying some lubricant from inside up past both pedals as well.

Another thought Andrew. There is another mechanical part of the clutch operation and that is the pushrod from the slave cylinder operating the release mechanism in the bell house. Unfortunately this is hidden so can't be visually checked.
Was the clutch pedal stuck solid or was there any movement at all? It does sound a mechanical fault rather than hydraulic. If you want I can give you the clutch system free play and height of the pedal from the floor figures.

Good morning Alan,
Apologies for the delay in getting back to you, work grabbed the best part of the week.
Thanks for all of your advice I really appreciate it, turns out it was a slave cylinder in the end, so fifteen pounds,a considerable amount of clutch fluid and pedal pumps later we are mobile again. So happy days Smile Thanks again.

Pleased you got it fixed Andrew. I don't recall ever coming across a seized slave cylinder. Wheel cylinders seize with monotonous regularity.
When my Land Rover started losing clutch fluid I suspected the slave so I had the master changed as well. Dunsfold said I should replace the flexible hose as well which was done and that was leaking. Slave and master were OK although they had been on the Land Rover for a very long time so really it was worth changing them.

Good morning Alan,
Just to let you know I had never had a slave stuck before so yes stuck pedal very strange, good idea about master though so will do that ASAP so all done. Not sure but reasonably certain clutch fluid approximately 6 or seven years old. As a novice I am slowly learning lots of things so as a matter of course am changing brake fluid as well this week. Thank you so much for all your advice I really appreciate it. I will keep you posted on progress.
Thanks again.

You're welcome Andrew. Don't forget, there's plenty of knowledge on this forum and you can ask away and no one will consider your question silly unlike another site I'm on. What someone doesn't know someone else will.
