At this stage, I'll have it re-ended or a new hard line run - whatever will fix it (I'm going to a driving school next weekend and just want it 100%). I'd like to avoid a trip to the dealer, since I don't think they're that great & they can't usually get me in very quick. Would a brake shop be able to handle this??
Your best bet may be to get a new hard line from some on line place and have it shipped. A good brake shop may be able to bend and make you a whole new line, I don't know maybe someone has more experience in this area.
I'm not sure how you did the swap but I have a limited amount of info here:
When you say the flair got messed up do you mean the nut that pushes in the flair or the flair on hard line end is FUBAR? If it's the line flair itself then you are gonna need another line I guess.
If it were me I'd first call around to a good brake shop and ask if they can bend you a new line or repair it. Or check with an on line vendor. Jamie may be able to help you out, getting something fast.
Good luck let us know what you end up doing.
