Re: bleeding a hydrolic clutch
You bleed it the same way as you do brakes. Pump, open valve, close, pump, etc. I have a hyrdo set up that I was gonna use, wanted to see if it was any good. Had water in it, but put some fluid in it, did the above steps, and it must work, I push the plunger and nothing moves. (Cylinder is rusted) Before you could hear air and fluid moving around.

Re: bleeding a hydrolic clutch
Usually to bleed it entirely, you need to pull the slave cylinder off the bellhousing, and angle it in a way that the bleeder points straight up while you get a buddy to pump for you.
When it is entirely bled, you should not be able to push the pedal down at all with the slave cylinder off the bellhousing, and bleeder screw shut (less mechanical play in the clutch rod to pedal connection etc) Once you put the slave cylinder back on, it will force some of the fluid up and into the reservoir, so don't overfill it while bleeding, you just need enough in there that it won't suck any air down into the tubes. After you've got the slave cylinder re-installed, then top the fluid off to the indicated line, and you'll be good to go

Re: bleeding a hydrolic clutch
do you hold down the clutch pedel and then open the bleeder , or do you open it as you are pushing the pedle down and not let it bottom out >?

Re: bleeding a hydrolic clutch
Do the same as bleeding brakes, have a buddy pump the pedal till it is solid, then have him hold it down while you crack the bleeder open. You should continue doing so until no more air bubbles come out of the bleeder. As soon as you crack the bleeder, the clutch pedal will fall towards the floor. Make sure you keep the reservoir full though, you don't wanna introduce fresh air into the top of the system, lol

Re: bleeding a hydrolic clutch
Glad to hear you got it bled
Bit of a pain in the butt the first time, but goes pretty easy after that
