Hello, i bought this Mercedes not to long ago and the clutch didnt work and the clutch master looked to be seeping. i took off the clutch and slave and found them completely backed up with gunk. I cleaned them out and tested them by putting my fingers over the clutch line holes and pressing on the piston, I definitely held pressure. I put it all back and found the flex line was clogged and leaking so I replaced that. Next I bled the clutch by connecting a line from the front right brake to the slave and had a friend push the brake pushing fluid and air up out of the clutch system.

We did this a few times but the clutch still has no resistance and just snaps to the floor without pushing out the slave at all? is it possible there is still a ton of air trapped in the master cylinder? I read somewhere else that these w110s are a pain to bleed.
