Hey guy,
I'm trying to upgrade my old OEM rubber brake lines to SS brake lines. The problem is that the old rubber brake line just wont unscrew off the hard metal tube that comes form the master cylinder. I really don't want to damage the hard line or the little S- shaped hard line that are connected together using the rubber tube. I am scared that if i apply any more force i'll end up rounding out the little 10mm nut at on the hard line side.
What would be the best solution to get the little piece of flex runner tube out without damaging the hard lines.
