Trying to bleed the clutch system after replacing the master and slave. I've successfully bled the system before, but not after replacing the cylinders. The fluid level in the reservoir isn't changing after topping it off, and I'm not getting any pedal pressure or fluid out of the slave. I'm bleeding by pumping the clutch several times, and then holding all the way down with a 2x4. Then I crack the bleeder screw on the slave just enough for fluid/air to escape. Then I close it up and repeat. Nothing but a tiny dribble comes out, and no pressure is building. The reservoir nipple and hose are free from obstruction, so I'm thinking that the new master cylinder may be bad. I tried adjusting the rod where it is attached to the pedal, but nothing changes. Here's my question: Even if there are multiple leaks in the line between the master and slave, the master should still be pulling fluid out of the reservoir, right? Anyone else had this problem and then fixed it?

 

its likely the pushrod needs to be adjusted so you have a half inch of clutch free play

 

That did it. The master is now pulling fluid from the reservoir. Thanks for the info.
