Adding a remote brake resevoir onto firewall

Many years ago I had a 1939 Railway Express Agency delivery truck. This was built on a '39 Ford 3/4 ton driveaway chassis. Not sure who built the body but it was somewhat similar to today's UPS or FedEx delivery truck bodies. This truck had a remote fill for the master cylinder on the firewall. Only one I've ever seen. Not sure if this was factory Ford or added by the body manufacturer, but it was original to the truck. As an aside, that truck was an original V860 3/4 ton. I may have photos, but will have to dig to find them.
 
I now have the brake fluid hose from speedway and the two hose barb fittings. Today I drilled and tapped the cap but now I need to fill these two breather holes. My thought is drilling them out just a bit to assure the hole is clean new metal, then inserting copper wire that's snug and then soldering it. I seem to remember heating something made of pot metal and watching it flatten into a molten puddle right before my eyes. I need some guidence here. Thanks.

But I still have to close up the vent holes in the cap below.

And BAT, In researching I read in a couple places that JB Weld does not stand up to brake fluid. I have thought about using that thread sealer that is recommended and drilling and tapping the vent holes for a set screw like a #4 . A very small pipe plug would be nice.....
 
Studebaker and Packard Hawks used a firewall remote reservoir. Did brakes on a Jensen Interceptor once and it had remote also. Owner supplied all parts and had them shipped from Britian. The reservoir hose needed replaced also. Owner had one sent. Really nice-looking hose, cloth braided with color trace like old wiring loom. If you're just looking for the bellofram in a small size like your drip cup. Check out some of the 80's upward Fords or other brands since they all went to hydraulic clutches and have small firewall mounted remote reservoirs.

The drip oiler has a brass tube down the center which holds the top and bottom drawn tight against the gaskets. I have 3 vehicles I want to do this to so I'm thinking the next one will have a removeable lid for a bellows diaphram. Also, Loctite recommends their 545 thread sealer for use on threaded hydraulic and brake fittings, so will thread the vent holes for #4s and get the 545..

Chris, dig away! V8 60 in a boxy delivery truck? I hope it was downhill both ways.

Took a bit longer to find pics than I had planned, but here they are. Unfortunately the remote mc fill is not in the engine bay pic, but was at the far drivers side of the firewall. Note what appears to be a governor under the carb on the 60!!

This was certainly no speed demon based on the shift points on the speedometer face.

For what it's worth, I bought a master cylinder from Rockauto recently and the cap is 2 piece. It would be suitable for a conversion to remote reservoir. I effectively did the same when converting the cap for use with a pressure bleeder. The middle hole can be tapped 1/8 NPT and fittings adapted to it.
Here is the make and part number.
DYNAMIC FRICTION 35555007 (355-55007)
A part number search finds it straight away.
Mart.

Mart, that is a great find! Still seems that their cap would have to vent somehow. I have been too busy at work to finish my system. Just need the loctite 545 to seal the soon to be threaded vent holes.
 
GB, the second part that screws into the main cap has the vent hole in it. It's quite a neat setup.
 
hi all ! i found my old mastercylinder and the cap aluminuin . not sure i can modify it . treads are kinda bass - turd . 1 1/4 by 16 treads . i would really like to find a metal cap .
while doing some research i found a military guy who sells a kit . not sure it would fit !
 
not sure the kit comes with the cap ! last pictures shows a brass looking cap, but its not seen on the other pictures . i was meaning to phone him ,but been quit busy lately.
 
I was just going to post that somewhere, sometime ago, I've seen a master cylinder with a white plastic reservoir that plugs into the top of the cylinder through a rubber grommet. I remember thinking it was neat that one could see the level without having to open anything up.
 
repaired my leaking rear left wheel yesterday ,only to find that my cap on the master cylinder is more like 1 5/8 . i had a friend measure the old one ,but he was not around so its a rough guess . i was looking for 1 1/4 ,but i need bigger !!!
