Ok, but how do you put the hose in a jar of brake fluid if it's attached to
the slave cylinder?

Quoted from Scott a few days ago:

"I connect a small hose from the left rear brake bleed valve, then to the
clutch slave bleed valve, and open both valves, so they are joined by a
small hose.
Then, pushing on the brake pedal, I pump brake fluid backwards and up
through the clutch hydraulic system .
Man.........that works like a champ !   "

yes, is the short answer.
the 'check valve' is the ole 'clear tube stuck into a jar of brake fluid/.
You use a clear tube so you can see bubbles as the come out of the system,
and also so you can tell when 'old-yucky' is turning to 'new fresh' , and
it's time to move on to the next wheel.
When you let the brake pedal return to the up position ..........the old
brake fluid can't flow backwards back up into the brake system, with this
tube in a jar method. The bottom of the tube needs to be well below the
surface of the brake fluid in the jar of course.
