Brake master cylinder leak (1 Viewer)

[Freeborn]

Got a leak coming from my master cylinder. Trying to figure out if it’s a) a master cylinder replacement, b) a pressure switch replacement, or c) an indicator of an issue elsewhere in the system. Check out the circled area in the pic. Open to recommendations.

You can replace those

I had same issues.... rebuilt mine with kit from @cruiseroutfit - problem solved CHEAP

Have you tried to tighten the switch into the housing? First I should ask is it leaking from the threads or the housing below? If threads try tightening if the housing then replace.

Went ahead and ordered a couple of aftermarket sensors from CCoT. I’ll give that a shot. Is it safe to assume that some thread sealant would be appropriate?

Are those supposed to be easy to unscrew/tighten? I tried using vice grips and couldn't unscrew mine off. Maybe they used some kind of thread sealant too

It's been a number of years since I messed with mine but I believe they are a tapered thread. I don't specifically remember using any sealer on mine.

Update:
Replaced the sensor in about 5 minutes. No more leaks. It was a surprisingly unmessy job even though I prepared for the worst.

Not easy to screw. Vice grips should be the right tool though.

I used a deep socket on a 1/2" drive ratchet and it came out no problem.

Great when a fix is that ‘simple’ huh!
I rarely get those...

@imyahucklbrry I triple checked the situation before I called it done. I was dumbfounded.
