I've tried all the ways to bleed brakes and clutch cyls. in my 18 years in
the business, and here is, by far, the easiest way to do it (and the way
I've done it for the past 7~8 years!) :

Way-cheap and long-lasting pressure bleeder: Total cost around $15~20 !

Go to your local gardening store, Lowes, etc., and purchase one of the small
one-gallon hand-pump sprayers intended to be used as a garden insecticide
sprayer. Also pick up a brake fluid reservoir cap from either an early
Vanagon or Rabbit (the plain one without a level sensor), and a hose
fitting, the correct size for the sprayer's hose. Drill a hole in the cap,
screw in the fitting, attach the hose. Now fill the container about half
full with fresh brakefluid. When you are ready to use it, screw the cap in
place of the original cap, pump the handle about 20 times to build pressure.
(I usually set the pump on the lower rim of the steering wheel) Then all you
have to do is go to each bleeder valve, open it and watch the old flow out
as the new goes in. No more helper needed! Works great on those odd things
that won't bleed any other way, and you are guaranteed an air-free job. If
anyone needs a visual of what it should look like, I'll be glad to send a
digital pic.
