Any BTDTs ? - How hard is it to manually activate the master brake cylinder

[Kneale Brownson]

I've never "pumped" a new one by hand prior to installation, but old MC's 
I've replaced will squirt residual brake fluid just like a squirt gun with 
just a little pressure on the rod.  Why did he remove the MC if your brakes 
were working fine on the drive to the garage?
