Two quick questions...I found out that my master cylinder leak is coming from the rear side fitting (three wires attaching there), is this a master cylinder replacement fix?
Also, I need to clean up the corrosion where it's been spraying around and rust bullet/ master series it or something along those lines, any advice on that?
Thanks!

I think you have a bad brake light switch.

Try tightening it to see if that stops the leak.
Is there a brake line fitting directly above the brake line switch? On mine I thought the brake line switch was leaking, but it was the fitting above it that was leaking. I tightened mine more and that stopped the leak.

Thanks for the replies...I'll dig into it tonight hopefully.
If it is the switch itself, does the new one screw in dry or do I use a sealant?

I just replaced my entire braking system on my dune buggy, including a new master brake cylinder and the switch you're having trouble with. Everything was screwed in dry.
