Stoptech Stainless brake line won't stop leaking!! I bought Stoptech stainless brake lines off of Amazon for my '99 Z28 a while back. I finally get to installing them and they were pure hell to get to stop leaking from the banjo bolt. I finally got them all to stop leaking except the passenger front. I have changed copper washers numerous times, tried the torque spec specified by Stoptech and even the spec listed in my Haynes manual. It still won't stop leaking. Anyone have any suggestions because I'm out of ideas.

I had this problem... but it also caused the shorter banjo bolts to strip my calipers. 
The issue is that you can't install the StopTech lines in the same position as the stock lines. The first part of the stock line ran in the recess cast into the back of the stock front caliper, but the collar on the StopTech line won't allow for that. The collar is too thick and doesn't let the fitting seat on the crush washer.
If you turn the new StopTech line so the black collar doesn't contact the caliper at all, everything should seat and torque correctly.

Wow, that sucks! You think they would have figured out something that detrimental before relaesaing them for sale to the public. I was seriously considering tossing almost $100 in brake lines because of it.
