| Could be that there's air trapped in the feed pipe from the reservoir to the master cylinder.
As the bore of this pipe is quite small and there is no pressure in it, it can be difficult to bleed the air from it.
The quick answer to the problem is the " Easibleed " or similar where you are pushing the fluid through from the reservoir using air pressure.
If you don't have one of those, try this.......
The technique I use to get rid of it is to half fill the reservoir, then every 5 seconds or so, move the lever a tiny amount, perhaps only 10mm of movement at the tip.
As you do this, look into the reservoir & you should see a small bubble of air appear from the hole at the bottom of the reservoir.
Slowly but surely, you willl bleed out any air in the feed pipe until you have only brakefluid in the tube to the master cylinder at which point you will notice a slight change in feel to the lever.
From then on, bleed the clutch circuit as normal.
This is a really frustrating technique but after 5 minutes or so you should be well on the way.
Don't be tempted to use bigger movements as all you will do is force the air back down towards the master cylinder putting you back to square 1.
Enjoy!
