Ok I have a 2006 350z enthusiest trim and the clutch went out so I installed a jwt stage 2 after the install I could not get no pressure at the pedal. I then figured it was the original slave had gone bad also replaced it still the same problem I kept bleeding and could not get nothing. I then called conceptzperformance and the guy said it was prolly the master had gone bad and I needed the upgraded wilwood so I got it in the other day got it installed and bled and still nothin I can pump the clutch and it feels like it has pressure when it gets to the floor and it returns about 3/4 of the way then stops I then have to pull it back to the top. Does anybody know what the problem could be? It was my first install but I'm about 99.9% sure I did it all the same way I took it out I had also seen a forum that had step by step with pictures and it was the exact the same way I did it.

 

There are already a few good threads here about problems bleeding the clutch hydraulics. Try the search function and I'm sure you'll find them.

 

If you're sure you fitted it correctly then I've got to agree with dcains and say that you're not bleeding it properly.

 

Try to do a reverse bleed where you push the fluid up the slave to the master to help gravity bleed. Also check your pivot ball to make sure it was installed properly and throw out bearing was put in place properly using the new bearing that came with the kit.

 

The clutch line (flexible hose) tends to collapse in some of these cases. Try replacing the clutch line and bleed again.
