volumetrically...all you should need is a bicycle air pump
that's all I've ever used. 

I'd be afraid to put must pressure into the reservoir.
just imagine the mess you'd have when the plastic tank explodes
in your engine compartment.

Steven :

Ok, call me paranoid.

I don't use a filter for my air tools, because they don't need one, and I've 
seen what comes out of the air hose even in the relatively dry climate I live 
in.  The 'cheap' air filters at best take the air down to 100% humidity at 
whatever temperature and pressure is inside the filter, which may be fine for 
painting, but leaves plenty of moisture in the air for conventional brake fluid 
to suck out, or to condense in the reservoir on a cold night.  I've also found 
bits of air hose in the screens in my air tools (which is a sign the hose is 
ready to be replaced).  You'll note that professional 'power bleeders' always 
use a diaphragm between the air source and the brake fluid.

I've had the experience of discovering I had no brakes _after_ starting down a 
steep hill into a dead-end.  It cost me a fairly decent TR3, and is not 
something I care to repeat.

So, I'm going to continue to make sure that my shop air comes nowhere close to 
my brake fluid, even after I install my new air filter (for painting).
