Clutch query - how much pedal travel??

1996 Discovery 300Tdi Manual

Hi all.
A couple of weeks ago, just suddenly, my clutch pedal went 3/4s of the way to floor before "catching" to change gear. Would partially come back up, but then wouldn't return fully unless I hooked my toe under it and pulled it back up. It would then stay up until next change of gear, then would do the same. Searched the site, concluded probably the master cyl needed replacing. Had it changed, was then ok for few days. Now today, after parking up the night before when it was all ok, drove off, but pedal suddenly travels about a third down before "catching." Gear change is still smooth enough, and pedal comes right back up ok now, but it's much more downward movement than I had before. Thinking may want a second bleed ? Does the new cylinder normally have to "settle" in, then bled again. Any thoughts anyone ?? Also, previously before any of this problem started, I only had to depress the pedal hardly more than 1-2 inches max before "catching" So my other question is what's the normal average travel before engagement resistance is felt ??
Thanks in advance.

Clutch release bearing failing maybe? Mine did after 180000km - friction disk was hardly worn! Also, Disco's are prone to release fork pivot point wearing through - it's a pressed steel item and hinges on a ball joint, and it wasn't strong enough.

Hope it's not as it's a engine or gearbox out to fix it, but a mate and I did it in a day and a half in Zimbabwe when my release bearing failed.

Cheers!

Is it loosing fluid?? It sounds like slave cylinder problems to me.

Well can't see any leaks, but reservoir was just below min after the new master had been fitted and run for a bit. That's what made me think perhaps there was still some air in system, hence a further bleed maybe.

fit a new slave cylinder, let us know the outcome.

What was the outcome in the end? Just got a 300TDI 110 and after 5 days got the same symptoms. It had a new clutch fitted at Mr Clutch 12 months ago so still has warrantee but don't want to get caught out with "the part that failed wasn't covered so that's another £500 if you please".

It has had the master cylinder changed by the place i bought it from as the cylinder was dry (should have checked) but the mechanic said it took ages to bleed it through. Didn't think to ask him if he used pressure bleeder - being his profession.

Drives ok and selects gears fine so long as you put the pedal to the floor and clutch fully engaged within an inch movement.

Thanks
