brake pressure switch threads? (2 Viewers)

[Brownd3max]

Does anyone happen to know what type & size of the threads are on those 2 pressure warning switches that hang down the bottom of the master cylinder? I'm referring to my '77 fj40. I thinking of removing them as there's no wires anymore from the PO, and they're leaking from their centers (not the threads). Need to find a suitable plug.

Fortuitous posting for me as mine are leaking too. I reused old sensors in a new master as it came with none. I also am sans warning lights so these are but plugs for the bungs.

Yeah, nothing worse than leaking butt plugs! LOL.

If I had to guess, I would say 1/8 BPT (British pipe thread).

I bought standard plugs 25 years ago... 1/8 BPT seems right.

I would second the 1/8" BSPT.

For folks interested in replacing the switches, look here:
