There's a little bleeder on your clutch slave cylinder, try looking underneath your car. And while you there, try this too. http://www.nicoclub.com/articles.php?id=251959

yea i tried that but nothing works.. i put my transmission back in my car after replacing the clutch then i went to try my clutch and i got nothing, the pedal just went straight to the floor, now i do not know what to do? did i f*** up the throw out barring and release fork? i dont see how i could have dont that but do i gotta take my transmission back apart? or do i just have to bleed my clutch system and if so, how long does it usually take, and what bleeder valve do i gotta bleed first the one on the transmission or the one on the box under my car...... thanks

Find a helper. There is a bleeder valve on the slave cylinder. Have you or a buddy open the valve, then the other pushes the clutch in. Tighten the valve, release the clutch pedal. Repeat until all you get is fluid coming out with no air. The easiest way to do this is to find a piece of tubing that fits snugly around the valve so you can see the physical air bubbles in the tube. So: Open valve, push pedal. Close valve, release pedal. Repeat. Don't forget to add more fluid to the reservoir if you get low.

bleeding it takes all of 5 minutes. find the bleeder valve using that link ( i assume it shows where) then here is how you do it. make sure your slave cylinder is full of fluid and you're going to have to make sure it stays full since each pump will lower the amount.. you'll need a friend for this too. when you open the bleeder have him push the pedal down, while its down close it. have hime bring the pedal up. then open it while he pushes down, close bring it back up, etc. just repeat til your clutch feels normal gain.

After re-reading your first post, after doing a clutch, the pedal normally will sink to the floor. A good way to check to see if you have a hydrolic problem or a throughout bearing problem is to just push in the clutch and have a buddy see if the slave cylinder is functioning properly. Also, try to push the fork and make sure there is resistance. Bleeding the clutch will take a while. ~ 10min. of constant doing it.

thanks for all the help guys i plan to try this tonight somtime... when my clutch gets pushed down the slave cylinder moves, trying to push the throw out barring but it just feels like there is not enough power behind the cylinder i can pretty much hold the cylinder with my hands its not that powerful. and i push my release fork and there is lots or resistance. so i guess that means that i just need to bleed the valve and if so do i just bleed the one valve that the slave cylinder is on..... thanks alot guys

The tube is a good idea. here is a good way get a cup a tube and a friend put the tube on your bleeder valve then put some new brake fluid in the cup put the tube in the cup so it is submerged. then with the bleeder closed have your friend pump the clutch 3-4 times then hold while it is held crack the bleeder valve then shut it after air or fluid stops moving or right before then after the bleeder is closed your friend can repeat the pumping. the tub in the cup lets you see the air bubbles and also does not let any air get sucked back up. also make sure you use new brake flood because it will absorb moisture from the air and no longer be any good so make sure the stuff you have still has the seal on it. also you can't mix synthetic and regular brake flood they do no work together.

Mine did the exact same thing. I replaced the clutch and the master and slave cylinder hoping that would be it. But no luck. After $600 worth of parts and labor, I found out it was one little $50 part. But I still had to drop the whole transmission again. So what you need to do is look up where the release fork is. There should be a little ball that the fork pivots on. If its broken or looks worn you should get it replaced. Here's a link for the parthttp://www.frsport.com/Nismo-3....html
