View Full Version : E30 slave cylinder bleeding

E30 guys... (Saige, Ben, and Eric!) have any of you guys dealt with BMW slave cylinders and their bleeding before?

Nope, would assume it's the same as bleeding brakes, one person pushes the pedal whilest the other opens and closes the bleeder screw. (isn't yours snapped off?)

New one finally, and BMW's creative ass engineers flipped the thing upside down so the valve is on the bottom thus doing a greatttt job of trapping the air!

unbolt it from the tranny, turn it right side up then bleed.
Saige, what does your bentley say?

But see how does one pump it unbolted from the tranny... nothing to put the piston against so it goes pop! and then it's new slave cylinder time :/
I second the Saige + Bentley notion... :thumbup:

I could look through my bently in the morning. I'm changing my fuel filter so, I could look at it at that time.

Beautiful! Thanks Ben! (Sorry I couldn't make it down today... :headsmash: )
I think I'm going to go ahead and order up a MC anywho as I found one for $65 which seems fairly reasonable to me... Plus I'm willing to bet after 10 hours of bleeding, that there's no way any damn air evaded me! I got entirely to creative in my process :cool:

I put my motiv pressure bleader on the system and go crack the valve open. I know you are suppose to pull it off and put a special tool to make sure the piston doesn't go flying out. I flush my entire system once a season and have never had a problem doing it that way.

If only I had a motiv power bleeder... Meh, already ordered a new MC as I'm 99% sure it's the culprit of this mess.
