Weeping Brake Bleeders

Does anyone have a solution to stop brake fluid from weeping around the bleeder valve threads?

This has been an ongoing problem with my front disc brake bleeders since I got the car. I've tried several different bleeder valves (Dorman among other no-name pieces) with no luck. It feels like if I tighten them any harder, they will snap off.

The next upgrade planned for the car is Hydro-Boost, which will probably make this problem worse.

Any ideas?

@Katfish - thanks for the reference thread. I'll try cleaning the seats and installing new bleeders and resort to Rip & Replace if that doesn't work. Which makes me feel like I'm about to go down the rabbit hole of garbage replacement parts again :-(


Bullitt-

  I wondered if there's a repair...apparently so but finding a way to buy just what he uses is a mystery

Since you've got nothing to lose, I'd take a brass hammer and give a bleeder screw a damn good clout straight in towards the seat and see if you get a wee bit more of a turn and if the damn screw stops leaking. It seems to be a failure to secure a good seating and this might solve the problem. Curious to see how you make out here. Good luck  :cheers:

Interesting. Looks like he also added some sealant to the threads as part of his fix.

Someone on Moparts was asking about the same issue.

Looks like they got it to stop.
I've had issues with fuel lines leaking, and the trick I was told was to put a little red grease on the threads to lube them and allow to thread past burrs, which worked!  But I wouldn't use any petroleum based product in a place where it might contaminate the brake fluid.
Perhaps teflon the poster used in that thread did the same trick as grease.
