54 dodge master cylinder modification

I have a 54 dodge with the original brake system. All the components are new, or like new. Wheel cylinders master cylinder shoes lines etc. The problem is they are original style with the one piece cast master cylinder under the floor.

Basically the master is one cast piece. It has a threaded filler on top and the reservoir is cast into the unit. It has one line out the back of the unit and a rod into the front that actuates the cylinder.



I have seen a relocation unit for the old vettes with under floor brakes.

What I think I can do with this unit is drill and tap npt hole into the side of the reservoir, add a flange fitting and hook a line to the bottom of a higher mounted tank.

Then drill and tap another line off the threaded filler on the top, connected to the top, or high on the side of the remote tank to allow air to escape back to the remote tank.

This way I should not have to worry about air bubbles keeping the lower tank from filling.

Skip the drilled and tapped hole in the side of the M/C. You don't need it. Use 5/16 line to go to the remote resovoir and the air will rise up naturally. Be sure to plug the vent hole in the threaded cap or it will become a drain for the remote res.

I just found this on ebay, where I going a little more rat on this I think this would be my answer. I see what your saying on the air clearing. I am a bit of an over engineer when it comes to things. Belt and suspenders type.
