clutch pedal falls to the floor

[ldyzluvdis06]

just installed a new slave cylinder on my 325is and after 5-10 minutes of bleeding it via a pump, the pedal still just falls to the floor and i have to lift it by hand. and i am still just pumping out like 80-90 percent air...

any ideas?

You mean you're using some kind of pump other than the mater cylinder/clutch pedal to bleed it?

What was the reason to change the slave cylinder?
If you thought it was faulty then it could be that your master is the culprit or you have a leak in the line. Try to check for any other leaks

it worked fine until i took out the original slave cylinder. i pressed the clutch with the slave out and it popped apart. so i ordered a new slave and now the pedal just keeps falling to the floor

I'm not sure what you mean. What popped apart?

The slave cylinder. The rod, spring popped out when I pressed te clutch.

How are you bleeding it? Like brakes? You have a helper I assume?

That sounds very odd to me. Any way you can take a snap shot of the old on and the new one on the car?

figured it out guys...i feel like a dumb ass too...lol... i didnt have the rod against the clutch fork. the clutch fork has a little play and was pushed down a tad.

but another question...

the clutch is releasing high. the car has no clutch adjustment. i would imagine with all this bleeding i have done i have gotten all of the air out of the lines, but, maybe not...?

Is it a new clutch or the stock one?

I had a feeling you were doing something strange. What you described is like bleeding calipers while you're holding on to it and not bolted on to the car. It just won't work.

As for the clutch releasing high. There may be some difference from the old one and the new. Meaning the push rod is a bit shorter. How does the pressure feel? Is it's a bit spongy? You may still have some small bubbles that have to be bled out. Last would be that if there is any play in the bolt holes that hold it down? loosen the bolts and push the slave closer to the fork and tighten. I don't know how it's bolted down so the last is just a guess if it applies.

It's a new to me clutch, but used. The pressure is good, nice a solid but not to stiff. And the transmission has studs and slave is held on with nuts, so that's not an option of pushing it down more.

It might just be since it's a differnet clutch, I was j/w if there was a detonate reason

Hold on......reverse some things i said.
If the push rod is "longer" on the new slave then it's keeping pressure on the fork keeping it not fully engaged when you release the clutch so it you have play in the bolts holding it down? Loosen and move the cylinder away from the fork. Again pending on the setup.

If everything else is cool then i wouldn't worry about it too much if at all. You will always get a different position when you replace stuff. Worry when it engages to close to the fire wall and it's not a new clutch.
