So I got all of the lines on last week, and started the car up a few days ago to work on the carbs. The next afternoon, large puddles of brake fluid lay on the ground by my two front tires. Inspection showed that fluid was leaking from behind the nut assembly on the hydraulic hard/steel "s" line that connects the caliper to the new brake hose (inside the fitting at the end of the hose). None of the others were leaking, just the two front lines at the older S-line connection. I called Orme Brothers, and they basically finished my sentence for me. This, apparently, is a common problem/occurance when fitting new lines to old hard line fittings. This issue has to do with the tapered flare of the S-line not forming a perfect union/seal against the new fitting in the new brake line. Orme Bros is sending me out some copper flare seals, which go inbetween the new brake hose female fitting and the old s-line male fitting. Is this a traditional solution? Safe, permanent? Two additional things. The front s-lines are going in a bit of a weird andle to the new brake hose, because the new brake hose fitting extends out about another 1/2in than the original did, causing the s-line to be slightly angled fundamentally (but the rotating nut assembly is threading true, straight inside the caliper). This could be part of the problem. I'm hoping that the leaks are due to imperfections in the seal, which can be corrected, as opposed to fundamentally different seal "angles" (45 degrees vs. 37 vs. whatever). One is a fixable problem, the other is an incompatibility. Thoughts or experience with this?
