I installed Stoptech stainless brake lines this weekend but did something dumb on the rear during the install, I loosened the banjo bolt after tightening it down in order to re-torque it. Don't ask why but I did...resulting in a massive brake fluid leak from the crush washers on that caliper.

So do I need to purchase specific crush washers for these brake lines or can I just run out to Autozone, Advance, PepBoys, NAPA, etc and pick up some generic copper crush washers?

 

any cush washer of the same size should be okay.

you tried retorquing right? I know its not ideal but most of the time they hold fine when retightened.
