3 weeks ago i installed custom brake lines just to the front (no rear brakes set up)that i double flared myself. A week later they held up fine with no leaks.I checked back 2 weeks after that and they were completely drained. I felt around and from what i can tell they are leaking from behind the bolt as if it was leaking past the flare and back behind the bolt.Did i flare them wrong? or is it possible i just didn't tighten them well enough or over tightened them? If i screwed up the flare will i have to go back and redo the flares?
