So... About 4 months ago I replaced my master cylinder on my 1950 3600. No problems.. Recently while doing some routine maintenance, I noticed it leaking at the large nut on end that goes to the brake line. It was leaking between the nut and the master cylinder. There is a copper washer between. I used a wrench and tigheten it up a bit (about 1/4 turn) We'll see if that works. IF not, it is going back to Jim Carter.
I suspect it will be fine..
