<VV> pressure bleeder

[NicolCS at aol.com]

Just a thought... I have a regular commercial pressure bleeder and also a  
hand-held mity-vac that came with a little bleeder reservoir.  I  always use the 
Mity-vac.  The pressure bleeder has to have a fair amount of  fluid in it and 
if you are working with DOT 3, 4, or 5, fluid it's hard to  flush for a 
change over.  You also have to be cautious to  periodically refresh the fluid in 
the bleeder so that you aren't putting aged  fluid in the car.  You also have to 
take the time to reset the diaphragm  and bleed the bleeder with each refill. 
 OK, 20 minutes later the  bleeder is ready but you have to get the correct 
MC adapter and install it  so that it won't leak. This isn't easy and usually 
involves little  chains and wingnuts.  Any error and the bleeder will dump all 
of it's brake  fluid your watertight trunk.  It's not fun to find your trunk 
floor 1" deep  in fluid plus the whole shelf under the MC is awash with fluid 
too.  (This  ruins the splatter paint finish).  Plus, since the bleeder fills 
the MC to  the top, there's always some spillage when the adapter comes off.  
None of  this is a problem with a conventional car where the MC is on an open 
firewall,  but on sealed trunk Corvairs, it's an issue.  Compare all that to 
the  vacuum approach.  The only headache with the vacuum approach is that the  
bleeder screws tend to put confusing bubbles into the clear vacuum hose and you 
 have to keep an eye on the MC level. To minimize the bleeder leakage, I put  
a little grease on the bleeder threads. Also, there's little to store with  a 
Mity-vac and it has many other uses.  I have both systems and my  hand votes 
for the vacuum approach.  Any one have a different experience  with these 
units?
