Leaking brakes, re-flare?

I got my stainless lines from Right Stuff and my distribution block from Classic Ind. which I think means Fine Lines. I had 4 leaking joints after installation. 3 sealed up after loosening and tightening 5 - 10 times. The last one was at the distribution block. after a dozen tries I called Right Stuff and they asked me to try a dozen more, which I did. It still didn't seal. I called them back and they sent me, free of charge, a stock steel line that goes between the distributions block and the little proportioning valve and that sealed after a few trys. The Distribution block is still a problem. The brakes seem to work fine, but the brake light on the dash doesn't go out unless you push hard on the pedal.
