Guys,
I am having a heck of a time attempting to get my brake lines sealed at the master cylinder. I was wondering if any of you have encountered the same issue? The two brake line connections at the Master Cylinder to the proportioning valve has a tiny leak. I dry off the lines and come back a few minutes later and drag a completely dry paper towel across the fitting threads and where the line comes out of the fitting and there is a ever so tiny moist spot on the paper towel and there is no dripping so far, but over time this cant be good. It's not even a drop, however my expectations is that the fitting will be completely dry? I have gone through three sets of lines and they all look good and two master cylinders,
I performed the tightening method where you tighten it a bit and back off 4 times and retighten, but I cant find the root cause of the problem.
