So ive replaced the brake switch twice the first one actually was frozen and the I replaced it with a Chinese one and it worked for a while and then kept the brake lights on so I went for a USA made NAPA Echlin one and it worked for a while but still stuck on. I’ve adjusted the throw on the rod and checked to make sure voltage wasn’t leaking to it. I’m at a total loss. Only thing I could think is that the brake fluid has junk in it and it’s gumming up the switches. The car sat for about 50 years when I found it and I replaced all the wheel cylinders, flex lines, etc. and rebuilt the master cylinder. Any ideas?
