1958 F.W.D. Posted May 13, 2013 Share Posted May 13, 2013 I want to make or buy a gasket/o-ring for the clutch master cylinder on The Mistress. The original one desintegrated years ago, and ever since then I have been making gaskets with gasket paper, but they keep blowing up. What material can I use that will stand up to the brake fluid??? Would a neoprene or nylon gasket work? What about a rubber o-ring? How about some old inner tube???? Suggestions? Thoughts? A penny for your thoughts??

farmer52 Posted May 13, 2013 Share Posted May 13, 2013 I don't think "rubber" and brake fluid are compatible. I would suggest neoprene. But I am no chemist.

1958 F.W.D. Posted May 14, 2013 Author Share Posted May 14, 2013 A mechanic friend of mine came up with a great idea- just cut apart a bottle (same one the brake fluid comes in) and make the gasket!!!!!Damn why didnt I think of that???

fxfymn Posted May 14, 2013 Share Posted May 14, 2013 Do you need a gasket for the screw on cap? If so, most of the original ones came with a cork ring. The "snap" type that close with a wire bail use a rubber gasket. Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

1958 F.W.D. Posted May 14, 2013 Author Share Posted May 14, 2013 Carl: it was explained to me that original materials (cork, rubber) will not work as today's DOT III brake fluid is too corrosive for those materials as opposed to the brake fluid of days of yesteryear.

41chevy Posted May 14, 2013 Share Posted May 14, 2013 The DOT III will swell up the rubber half again bigger. My 1941 Chevy has the same type of master cylinder with a screw in cap, I went to the local swimming pool supply and found a Teflon seal ring for a pool pump. It is impervious to everything from brake fluid to chlorine. Cost a whole 59 cents.
