correction - MASTER CYL bleeding question....

So, I've always bled masters by putting short lines from the outlet ports looping back up into the reservoirs and pumpin about 1" slowly repeatedly til no bubbles showed.

However, the master I am currently workin on came with plastic screw-in caps that are supposed to be used for mc bleeding. So, it says to install them, then do the same 1" slow pumping til bubbles are gone.

Anyone ever used the plastic caps that plug the ports to bleed their master cyls? I'm not quite sure how this works, but apparently it does...

Thoughts? Thanks.
