Master Cylinder?
Well I was really inspired after the Richmond Nationals and all those high quality cars so I spent most of the day working on my '29. In particular I have been having a lot of frustration with my brake lines. It took a LOT of pumping of the pedal and wasting a lot of fluid but I finally got fluid to come out of all the wheels with the cocks open. Then I started to eliminate the leaks. Due to a good chat with the guy from the Flatlander shop in Norfolk at the Richmond show (he displayed a really neat 3-window 'glass body all set up ready for interior and paint and had the same kind of thru-frame front brake lines I got from Speedway) I tried using teflon tape. Anyway he advised a full 3 1/2 wraps of teflon tape on leaky fittings and I tried that today. I was doing fine eliminating one leak after another and starting to get slightly optimistic after a long frustration with the brake lines and finally I got rid of all the leaks but one. The problem is that I have what I think is a Corvette dual chamber master cylinder and it has FOUR outlet holes of which I only need two and the other two are supposed to be plugged by threaded bungs. I sealed one off with teflon tape but the other still leaks after three tries with successively more tape each time. Now I have totally rounded out the shallow Allen-wrench hole in the bung and it is in so tight now I cannot get it out or tighten it and it still weeps a little when I pump the brake pedal. My last resort may have to be to pull out the whole MC and chuck it up in my 6" vise and chisel out the bung or perhaps tighten it by applying a small cold chisel at an angle along the edge to tighten it more. The problem is I will have to loosen several other fittings to get the MC out and maybe have problems getting them sealed again. How about it out there, what can be done to work with a rounded out Allen wrench hole? On other threads some of you have divulged some really neat tricks for other problems. What about a rounded out Allen wrench socket hole. I am considering sawing off an "easy-out" where the diameter will be close to the size of the rounded Allen socket, which is disgustingly shallow. Maybe an easy-out will work but then that is only getting it out, how to tighten it later? This is the final leak in my brake system and if I can get this sealed I can finally move on to the next problem on my chassis! Suggestions?
