Leaking brakes, re-flare?
Suggestion - After rounding off some of the chrome over brass Holley fuel lines, and have them still leak, I figured the friction between the threads were not allowing it to tighten as much as I needed.
I put Teflon tape on the flare nut threads to reduce friction, and succeeded in easily tightening them more, - sealing the leak without rounding the nut .
I have used same on stainless lines . (I will never use stainless again).
Remove all the tape visible, - cuz everone'll roast ya , "dontcha know flares don't use Teflon tape,- idiot".
Just smile .
