Default Please help!!

So I bought a new clutch slave cylinder after changing the clutch (oem). Installed it today and now it won't bleed the clutch. The pedal springs down and won't come up unless I pull it back up. The hell is the problem cause I haven't found anything about this with a straight answer.

You either have a leak, air in the system, or you didn't install your clutch correctly.. Check the reservoir level. Does it drop after you pump the pedal a bunch of times?..

he prob isnt bleeding it. after you drain all the fluid out by replacing the slave, you will manually have to pull the pedal up until it starts to build pressure

Clutch is fine and we are bleeding it. The problem is it's not building pressure at all and weve been bleeding it for awhile

Are you using a power bleeder or the ol' "pump it up.... hooold it" method?

The only 99% sure way to bleed a Z is with positive pressure, not the pedal method. Or at least Motive has paid itself off many times over in saved brake fluid and time spent bleeding.

It is the old school method. We have gotten a little pressure not alot. And what is the motive?

Googling it will show what it is but here's the one you need:

So I saw it's about $60-$100. That's not really an option for me right now. Since we're starting to get pressure should we keep bleeding the system. BTW the is an 03 and just got a new slave and master cylinder today.

$22....does same thing just not quite as eloquently. I used one of these until I bought the Motive. Gave away the HF one after using the Motive once.

It did some of the time not all though. Is there a particular system for the z? I used to own an eclipse and bleeding that was no problem.

If the fluid level is going down while the system is closed, then you either have air in the system or there's a leak somewhere. Are you sure you connected/installed everything properly? Pick up the bleeder Mic suggested and try that first. If that doesn't work, I'd follow the course of the whole system and look for leaks.

I did see something about a master cylinder adjustment rod needs to be adjusted all the way in for it to open up to allow fluid to flow

did you mess with the position of the old one when you took it out? if not, or minimal, try to make the new one look just like that one

read this first

and then to the others below

1. Move the driver’s seat back and get in the floor board on your back.
2. Remove the fuse box cover.
3. Locate the clutch pedal assembly.
4. Notice the pedal has a fork attached to it; the fork is connected to a rod that goes back toward the firewall.
5. Insert the tip of the screwdriver into the fork and brace it.
6. Place the 12mm open end wrench on the nut located directly behind the fork, on the rod.
7. Break the nut loose.
8. Grab the rod with your fingers and turn it clockwise.
9. Re-tighten the nut.
10. Replace the fuse box cover.
11. Enjoy.

I went 4 turns and it ended up perfect, but you may want to start out with 2 turns and see how it feels; you do not want to turn it too many times or the pedal could end up too low to the floor, in which case the clutch would not be disengaged when you fully depress the pedal. If this were the case, the car would begin to move in gear with the clutch depressed, or stall.
