Default Bleeding clutch

I finally have my new clutch installed and found out my slave cylinder was leaking. I just installed the new one but don't have any pressure in my clutch. I tried the manual way having someone else pump the clutch while I turned the bleed screw, then I got a pressure bleeder and have cycled through about 12 oz of fluid but still have no pressure in the clutch. Do I need to just keep bleeding it or could something else be wrong, like the master cylinder?

I just bleed mine after disconnecting to reinstall the transmission using a power bleeder. My clutch pedal never lost pressure, it had pressure when I pushed to the floor before bleeding and also after when I pulled it back up and pumped before bleeding again. I don’t have a lot of experience with this model yet so not sure about the master cylinder.

I just went through another 12oz bottle of fluid. If I pump the clutch a little pressure builds but never to where it will come all the way up. As soon as I start bleeding all the pressure goes away.

Keep pumping, the air will work itself out eventually. I’ve had my pedal snap to the floor and stay after my last slave install. If you can have someone else pump while you tend to the bleed valve I find that works best.

A couple of questions:
-when pressure bleeding, did you fully push the clutch pedal in and hold it for the duration of the pressure bleed? The manual asks for this. I suspect it is because otherwise air may get stuck in the master.
-when manually bleeding, there is usually no pumping, it's different than bleeding brakes. Open the bleeder, push the pedal to the floor, close the bleeder, release the pedal. This will move the air in the line toward the bleeder valve.

Apologies if this is what you've already done. I did not interpret this from the discussion.

Good luck!

I did the manual bleed a few times then close the nipple and pump the hell out the pedal!! You will feel it coming up, then do a bit more manual bleed then close and pump the hell out the pedal again, it's worked for a few people I've recommend who have struggled even with a pressure bleeder , let us know if it works ?

I used a piece of wood against the seat and the clutch pedal to get the pedal depressed. Used a pressure bleeder to push old fluid out. It took a few seconds of bleeding the old fluid. Tighten the bleeder and removed the piece of wood. Pulled the pedal back up and it stayed there. All done.

I recently was having problems bleeding the clutch in my 928 and a few of the guys recommended reverse bleeding which ended up working really well. The 928 clutch MC is at an angle that's difficult to bleed using a traditional Motiv pressure bleeder. Might be worth exploring on the 996.

Here's the thread. Scroll down to post #8.

If you don't already have a power bleeder, I suggest buying one. It is one of my favorite tool purchases ever. Bleeding brakes was something I dreaded, but now its a breeze.
