Can anyone explain the concept of a master brake cylinder and how to convert to a remote fill?  I am assuming all that would be necessary is to install two fittings in the existing main reservoir, run two lines to a remote fill. One line would run from the remote fill to the main master cylinder and the other line would run from the main master cylinder back to the remote reservoir to vent the remote. Is this correct? The goal is to be able to fill the main reservoir from the fireball opposed to under the floor boards of a 56 Ford F-100. I will eventually swap out the front drum brakes for disk brakes so this is just a temporary fix, one of them that could last years.
