I had everything hooked up and was going to bleed the brakes and noticed most of the fittings, if not all of them were leaking. Even the fittings that came on the brake lines I bought from Cruiser Corps. I hope I just need to loosen and re-tighten and repeat a few times to get those to seat. I feel the double flares I did to plumb in the Wilwood P-Valve with the titan tool were pretty good. I bought some 3/8 male fittings to connect the proportioning valve to the system and wondering if the leaks in this area were due to the wrong fitting. The original fittings (M10x1.00) are not fully threaded and are longer than the ones I bought. Could that be my problem at the proportioning valve? As far as the others, is it just a matter or tightening them, but not too tight?
