My 62 LeMans has a single-circuit MC, running to a 4-way splitter. The PO ran a new hard line from the splitter to the rear brakes & I have a slight leak where the hard line connects into the splitter block.
Should I suspect the line since it's new & has been fiddled with recently? Or should I swap the splitter block since it's 47-years old?
More importantly, is there a good way to tell what's bad, or do I just replace them both since they're cheap?
If the components are cheap and you're at all concerned about the safety, I'd swap out anything even vaguely suspicious. You'll have to bleed 'em every time you touch 'em, might as well get all the work out of the way and only bleed them once, right?
If I were to guess, I'd say the flare wasn't shaped quite right on the hard line and that's your problem. Have you tried tightening it just a bit more? Ghetto, but it can help form that steel line inverted flare the rest of the way.

You could use this as the impetus for installing a dual circuit, maybe even diagonally split, system.
Thanks. I hope do a serious brake upgrade in the future, but for now getting it on the road is enough.
Clem, your advice worked! I was hesitant to tighten it any more, as I though I was near the stripping point of the brass, but another 1/4-turn worked - for now anyway.
