"Buggered" inverted flare nut on brake line
Right front on my 66. Replacing brake hoses. The inverted flare nut was previously damaged, this time requiring vise grips, as the flare wrench no longer fits.
Has anyone had any luck, cutting the flare off close, straightening the tube, installing a new nut and reflaring the end (double flare of course)? Seems like there is enough tubing to do it, just don't know what I'll face straightening the tube an making the flaring tool fit.
Also, aren't brake lines a different flare angle than plumbing? One is 45 degree the other (brake lines) is 37 as I recall. Is this right?

Nope, inverted flare is 45*. You may be thinking of the 37* JIC hydraulic (oil not brake fluid) system.
Your natural gas and water lines in your house use standard 45* flare.

I had the same problem a few years ago. Had a brake hose take a crap on the left side, and of course in good form, went to replace the right hose as well. The nut would not budge, and when it did, it twisted the line, and fractured it.
The line is very strong, and just trying to bend it up to get a flare tool in there was a pain.
I just ordered a new line, and installed it. It was an AZZ pain, as it is routed from the junction block, arond the front cradle, up the side of the frame and out to the wheel.
Doing this with the radiation and shroud in place required patients, and some tweeking.

Thanks everyone for the replies. I was able to get enough of the line straightened to get both the nut and the double flaring tool on it. I have not yet cut it and flared it (I'll have to make the cut with a dremel tool, as there is no space for a tubing cutter). Though I'd practice on a few generic replacement lines before trying to cut and flare this one. I'ts a one shot deal right now. I'll let you know in a few days how it went.

AN fittings are 37* - I have Imperial Eastman flaring tools for both 37* (AN) and 45* (SAE) fittings.
