Hi all,

I have the master cylinder off my `82 cb750k right now, for cleaning and rebuilding.  It's all cleaned and rebuild now, so my question is this: is there an easy way to test it and make sure it works before I put it back on the bike?  I figured that if I pump the piston by hand, it should draw fluid from the reservoir down into the cylinder, and fluid should eventually come out the hole that normally connects to the brake line.  I did that, though, and nothing came out.  Any thoughts?
