My '70 bug has a brake fluid leak after I replaced the master cylinder. When I installed the new MC, the brakes were still not right. Since I was tired, I called it a day. When I started working on the car the next day, I found that all of the brake fluid had leaked out. From the looks of it, the fluid is leaking out near one of the two brake sensor switches. The switches were screwed on tightly, and the threads seemed to be the right size, so it didn't seem like there would be a problem. Obviously I did something wrong.
Here are my questions:
Is it possible that the fluid is actually leaking out through the switch itself? (It doesn't *look* like there's any place for fluid to leak out.)
Should I have used some kind of sealant on the threads of the switches - maybe teflon tape? It looks like there was some kind of white sealer on the threads, but none of the books I have (Chilton, Haynes, Muir) mention using any sealer on the switches. The "Bug Me" video doesn't say anything about it. None of the Bob Hoover articles I've combed through mention anything about it.
Can any of you give me some ideas on how to solve this problem?
Thanks for any help!
