what am I doing wrong?
 

trying to bleed the clutch after installing new master and slave cylinders. nothing doing. pedal just flops - no juices flowing.

what am I doing wrong? yes, I did "bench bleed" master cyl and it was squirting good when I hooked it up...?

OK. I'll answer my own question.

When installing the clutch master cylinder grasp the rubber hose that leads from the tank on top of the brake master cylinder and squeeze it, all along it's length. This will remove the air bubbles. Can't expect to bleed the system when you're feeding air to the m/c.

Before you attach it to the firewall connect the steel line to it, open the bleeder on the slave cyl and give it a few pumps by using a screw driver (or whatever). The clutch pedal does not give the m/c much of a "stroke." This way you can give it a full stroke. When I did this the system burfled, then gravity bled, just like it should have :)

Excellent!

I did not replace a clutch cylinder yet. So no experience. I think I would have suggested to pump fluid up through the bleeder. But you found a way that works.

What would you use to do that?

this works great:
