WTF is wrong with my clutch

It's a 1995 D-90 SW. When driving, the clutch holds fine, there is no slipping, grinding of gears or anything that would indicate a problem. Recently I started to notice that the engagement point was changing on certain gear changes. Initially i figured "well it's a land rover" and that was just yet another "feature" of British engineering. After playing with the clutch. here is what it's doing:

If I hit the clutch under normal pressure and speed, like you would in daily driving, it works fine 90% of the time. I get normal pressure and normal engagement point. If I gently and slowly push the clutch, it goes down to the floor with zero resistance and won't disengage the clutch. If i let it back up and press it normally immediately after, it's fine again.

There is no fluid leak that I can find and there is fluid in the reservoir. The weird thing..If I press it normally and hold it.. it doesn't "bleed down" and eventually reengage the clutch. it will hold pressure fine.

I don't understand.

So it's a new master cylinder you're thinking?

You need to replace your clutch master and slave cylinders and the hose wouldn't hurt as well.
When you replace one and not the other cylinder, than the old one seems to go shortly thereafter (in most cases).

Great advice. I grew up with British Leyland hydraulic clutch systems, and replaced the master a week before a vacation in France. Slave failed 100 miles after I got back to England....on a Saturday afternoon, just before the local Halford closed.

Yes, replace everything at once, flush and bleed well. Only use OEM cylinders. The aftermarket ones have a very high failure rate.

The slave cylinder is quite easy to change, unless you snap off the "death clip", to avoid that do not pull the cylinder rod away from bellhousing.
The master cylinder is a little more difficult, mostly because lack of space. If you want to work at your ease remove the wing, I did that last time I changed mine and it made work may be longer but pita free.

Do as said before, use genuine LR parts.
