<VV> Master Cylinder

[Bill Elliott]

No disadvantage (other than the mess and potential paint damage) and in 
some cars a mandatory step. In a Corvair it's a really good idea though 
not 100% necessary.

Basically what you're doing is getting all of the air out of the master 
before mounting it. You connect hose(s) from the master output and place 
them in the reservoir. (Many new masters come with plastic fittings and 
hoses just to do this...)

 Fill the reservoir with fluid then slowly compress the master while 
holding it horizontal. Then release. Keep doing this until air bubbles 
cease coming out of the end of the hose(s) on compression. Easiest to do 
in a vise.

Be VERY careful not to get the fluid on any paint... any fluid worth 
using (for anything more than a trailer queen) will aggressively attack 
paint.
