I don't think the factory did it that way - they would have done it the 
same as the brakes from the Master.  But they used a higher pressure and 
hence flow than is safe with an EeziBleed, and I have read of workshops 
with similar higher-pressure equipment also do it without problems.

But for us poor owners yes reverse filling has worked for me as well - 
albeit not every time.  The first time I did I connected the EeziBleed 
to the clutch slave until I could see fluid in the master, then topped 
off as normal, and had a perfect clutch.  The second time I did 
something else recommended and that was link the right caliper and 
clutch slave nipples - they are the same size, and while someone gently 
operated the brake pedal opened and closed the clutch nipple - whilst 
keeping an eye on the level in the brake master of course.  Again a 
perfect clutch, and that is despite the conventional wisdom that says 
the bleed nipple has to be at the highest point in the cylinder - which 
it isn't with reverse filling/bleeding.  And when that hasn't worked, 
both for myself and others, then wedging down overnight has.  Even 
though almost all the run is vertical it seems that having the front 
higher than the rear makes the difference.
