Changing a transmission in an 85 Adventurewagon Vanagon ( FS , btw ) ......
got the new trans in, notice the clutch slave cylinder rubber boot looks
like it might be full of fluid .............I squease it.......sure enough,
full of 'black water' ......
old brake fluid that has turned to water almost, and very thin ......so
obviously slave is shot.

I put on a good one ......but it doesn't want to bleed.  No matter what I do
.........won't bleed .........air keeps getting pumped in by the clutch
master cylinder ..........( .which should be replaced to obviously )
.....but I need to just get this van moving and parked outside .....to get
another job in and started.
so ............I don't think I've gotten to use this trick in about a dozen
years.

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 !    About 15 strokes on the brake
pedal..........
I close both valves........nice solid feeling clutch pedal ........hot dog,
she's fixed and working in that department for now !

so if ever.........you can't get a clutch hydrucalic system to bleed, using
any push-on-the-pedal method ( and they are hard to get started with a new
clutch master cylinder if you are using a push-the-pedal method )
..........remember this trick, cause it really works.

 pressure bleeder would transcend all this ..........and I do have one, I
just like the feeling at the pedal when it's working right ....
You can get an idea of how good any master cylinder, clutch or brake, is, by
how it feels during bleeding with any push-down-the-pedal method.
Vacuum bleeding............seems there'd be risk of sucking in air to me, so
I never use that method.  But try this trick sometime when you need to.
