Default Leaky breaks

Getting ready for my FAA inspection and I noticed my break lines were nearly leaking where the lines attach to the cylinders. My issue is they are leaking at the fitting. If I tighten then then the break lines get in the way of each other. Anyone else have this issue?

Not sure I understand what you are describing.
Tightening a fitting should not interfere with anything.
It's kind of hard to see in the picture, the brake line is looped around the leg once and there is plenty of room to tweak it in almost any direction.
Can you be more specific?

Yes. You may need to go another turn with the fitting, or remove it and put some (more) thread lube/sealer on the threads and install it again.

Did you use sealant on the threads?

It sounds like you are describing the fittings on the cylinders at the pedals. Am I right?

Several times I had to drain the brake lines to tighten up a fitting. It would be leak free for awhile then a drip would start again. After several attempts without success I finally got some Lochtite sealer to use on the male threads. No more leaks. I can't remember the Lochtite number, maybe 606 or 656 something like that. Do a search and you should find it. Somebody posted that this is what A guy at Matco recommended.

Jesse,

Yes it is the blue fitting connecting to the pedal brake cylinder. It looks to me like the leak is at the cylinder and I am not sure I can spin those around another full rotation.

You may need to back it out and lube/relube it and reinstall it.

I had the same issue. I took all fittings off the master cylinders near the pedals, cleaned them, and applied Loctite 567 to them. Seems to have done the trick but I'm not flying yet.

Use any "gasket maker" sealant and you will never have a problem. Here we get Wynns Gasket Maker in most Auto shops.

If you do not do it when new, you have to take them out, remove the fittings, degrease the threaded holes and the fittings properly and then apply the gasket maker and install.
