I'm attempting to extend my brake lines but ran into an issue. The bracket where the metal brake line turns to the rubber 1 is impossible to remove. Almost striped the head because i can't find the correct box wrench sixe. Some where between 9 and 10mm. I hit it up with a lot of PB blaster. Any other tricks i should try?

Any and all advice is greatly apreciated!

 

Try a 10mm 6 point socket and pb blaster. Box wrench can "spread" on a tight bolt.

 

I cant fit a socket on it unfotunatly. The metal brake line comes in from the top and large braket on the underside

 

I would give the pb some time. Sometimes you can tighten it and then remove it. Might break-up any crud in the threads. Good Luck!

 

I just PBed it and used my Craftsmen professional adjustable wrench on it, grips to anything and doesn't strip it.

 

BIG set of vice grips usually helps me out or drill the head and use an ez out
