Stovebolt.com Forums The Shop Area Driveline Single MC remote fill

Looking for info on a firewall mounted remote filler for a single master cylinder. I searched the forums but couldn't find anything. Has anyone done this? I was thinking of drilling and tapping a stock MC cap for a 1/8" barbed hose fitting and running a hose to the firewall reservoir. Any ideas?

The stock cap has a vent hole drilled through the side of hex which will need to be welded shut or have a lead BB pounded into it.

OK thanks. Can you think of any reason this couldn't work? I know that a dual master cylinder would be better. Maybe eventually but for now my concern is an unnoticed leak that drains the under floor MC. Out of sight and out of mind.

Find an expandable rubber freeze plug that is a snug fit in the M/C fill hole and drill the center bolt for a small hose nipple that can be pressed and/or silver soldered in. Attach your remote reservoir hose to the nipple.

So I opened the master brake cylinder on my '54 and it was EMPTY! Out of sight and out of mind so I installed a remote reservoir from Wilwood: Remote reservoir [speedwaymotors.com]

I had an older Ford truck with the master below the floor and I drilled and tapped the screw in cap, installed a barbed hose fitting and remote reservoir on the firewall. Not hard to do and worked pretty well. You do need to make sure that the master cap is sealed well which they generally are not because they are vented anyway.

A slight modification to a rubber expandable freeze plug makes it a good adapter for a master cylinder when going to a remote reservoir. Install a larger diameter carriage bolt to expand it, and drill and tap the bolt for a flexible fill hose from the reservoir.

That looks like a good idea .I also noticed in your picture the round black ball .What is it from and does it help the wipers?

It's a vacuum reservoir that I bought on Amazon but I haven't tried it yet
