bench bleeding clutch master cylinder

[ForOffRoadDriving]

is there a way to bench bleed the clutch master cylinder like you can with a brake master cylinder or am i better off to wait until i have the trans back in the truck to fill it up and bleed it? it seems like if i fill the resevoir and push in the clutch push rod while its in the vise then its just going to get hard since no fluid can escape out of that quick disconnect end. oh yeah, its on a 1994 3.0l ranger with a m5od-r1.

do you have the line from the master to the slave out of the truck too? from what i read you need someone to push open the quick connect while you push the piston/rod so fluid can escape.

I have a chunk of steel tube that after I cut three sides off it
that I cut a hole in and drilled two holes so I could mount a slave to it while the chunk of steel was clamped in my bench vise.

Above my vise is a shelf and I usually hold the reservoir up with a bungee or a piece of string or wire whatever is handy.

the master is mounted nose up.

and I use a piece of angle stick as a lever to push the rod UP
AFTER I have blocked the port in the dry break open.

I do that with a female half that I couple to it and IT has
a length of clear vinyl tube that runs up and into the reservoir

Just pump the lever until the bubbles stop.

Oh, btw, the "Barp spring" has been removed from the female coupler
so you have to hold them together with your free hand.

The same effect can be accomplished with two people, without
any of the other stuff, but unless you like taking brake fluid showers....

FWIW I keep a spare master, line and reservoir hanging from a hook
on the wall of my garage, it's prebled and I can install it in 15min if
the need arises... I've got another just like it in my "roadtrip spares" box
