Default Bleeding clutch, need fast help!

So im replacing the clutch/flywheel/master cylinder in my car and am in the process of bleeding the system. We've been bleeding and bleeding this thing and im still getting no feedback from the clutch pedal. What are some things i can look for?

So, you have everything put back together now right? You're just on the final step which is bleeding it?

yeah, but now we pulled the tranny back off to get better access to the slave to bleed it. We bought a vacuum pump and are going to see how that works

nope...

Also, now that we've pulled that transmission back apart to get to the slave to bleed it easier, the slave started leaking around the inside where the shaft goes in...

Did we F*ck up the slave now?

Basically we were bleeding it, then heard a pop (air/fulid releasing) and now it leaks when we put the clutch to the floor

I'm sorry, I meant bench bleed.

You should be able to bleed the slave with the tranny installed.

Just use a 7/16" socket with a ratchet. If you open the beeder, it will leak from the bell housing, that's normal.

Well initially we were bleeding it with it installed... but then we decided we werent getting anywhere with it so we pulled the tranny back apart to get to it and bleed it easier.

The problem happened the first time that we actually got some pressure back in the clutch pedal with the slave out. Once i pushed it in i think it blew the end of the slave off (just a little bit) past the seal and thats when the leaking started. So would that have ruined the slave?

Ouch I see, yes I think a trip to Autozone might be required.

When you reinstall the trans and new slave, crack open the slave bleeder when re-installing the trans.
This way you won't hurt the slave and it will make it easier to install the trans.

Once everything is reinstalled, Just make sure to close the bleeder before you re-connect the master cylinder's hydraulic line.

Sounds like you pushed the peddle with the slave out-big no no since it will over extend.

Also sounds like your doing the old hold peddle down,crack bleeder which is the wrong way too.Crack bleeder,push peddle down,close bleeder is the correct way.

The GM manuals suggest cracking the bleeder on the slave and attach a rubber hose and insert free end into a bottle of brake fluid (with transmission installed). I have also heard that time and patience is important with these GM hydraulics.

What exactly would that accomplish?

I was dumb and did the same thing this weekend; I installed a monster 3 and everything went silky smooth until I went to bleed it...I was trying to do it as if I was bleeding my brakes. I'm used to doing LT1 clutches and the external slave.

Open bleed screw, clutch pedal to the floor, close bleeder screw, pedal all the way up. Rinse repeat, took me about 30 mins and a pint of brake fluid to get it perfect.

Only downside is, I don't have any paint left on the trans tunnel on a spot about 10 x 10 inches from brake fluid getting on my gloves and rubbing the paint off. I'm not worried about it since its under the car, but I am going to get some NBM spray paint and cover it back up.

It would at least accomplish keeping brake fluid from inside the bellhousing, and all over the bottom of your car.

Of course I only stated it as a GM service manual fact. No tube from bleeder screw is entirely up to you guys. (Yes I will use one to route the fluid away from the bellhousing)
