When bleeding my clutch on 1991 Discovery 1 there is no liquid being expelled via the bleed nipple on the cylinder. When the pedal is released the fluid level in master cylinder lowers significantly.
There is no leak showing up on the ground below the vehicle.
Appreciate any informed opinion on where the liquid might be going and what might have failed.

I did successfully fit a new damper about 500 miles ago and the system bled normally. However recently the gear change has been getting progressively difficult again and the pedal quite soft yesterday ,but not completely.

thanks

The fluid has to be going somewhere, so if you are not seeing it under the vehicle, it has to be inside around the plunger attached to the clutch pedal, you will find the carpet wet under the dash, if this is the case then master cylinder is suspect
 
It could also be going past the seals in the slave cylinder and into the bellhousing. Can you see any oil coming out of the drain plug in the bellhousing?

But it is more likely to be the master cylinder.
 
those from above,... or if the level doesnt drop the seals in the master cylinder are gone and a bit of a rubber blocks the otlet...anyway the simplest(but not the cheapest) is to put a new master cylinder first to rule it out and save yourself from some struggle
 
thanks for the advice. The underside of the housing looks to have liquid on it although none on the ground ,so I'll try replacing the slave cylinder first as it's cheap and simple from what I read.
 
I ha trouble bleeding mine after changing clutch. Changed master and slave and still wouldn't bleed. There is a one way diaphragm valve thingy between master and slave. I bypassed this and it bled to perfection immediately. Been meaning to get round to getting a new one but 1000 miles later and she's running perfectly.

Just to update ,I fitted a new slave cylinder and then bled the system with a one man kit which appeared to quickly produce an outflow with no air bubbles.
There is no fluid being lost and the pedal is firm with very little free play.However,when the pedal is down the clutch is engaging very close to the floor on release (dragging ?).
Reverse particularly and often 1st can difficult to engage.
It would seem like a damper problem were it not for the pedal engaging so close to the floor.
As said the pedal is plenty firm enough. Any best guesses for cause ? I gather the clutch is self adjusting (Discovery 1 1991)
 
The only real adjustment u can make urself is the shims between slave an bell housing, remove or add as necessary. Also the bolt that the pedal hinges on is offset, spin this to give a higher biting point.
