Rusted rear brake hard line just cracked.. What do?
I was changing out the OEM brake lines with SS ones. Successfully changed out the fronts, but the rear hard line was so corroded that it cracked as I tried to loosen the flare nut. Looking at the condition of the hard line, I imagine the whole thing should probably be changed out; I don't think there's even a good spot to cut and flare.
If anyone has any experience changing out the rear hard lines, what's the best procedure? Can I do it without lowering the subframe?

This happened also to me last winter. If you want to replace hole line and going diy route your options are:
-New oem line from Honda (if they still sell them), but replacing job includes lowering the subframe.
-Copper nickel brake line and bending it yourself. This way you don't need to lower the subframe.
I bought 4,75mm (3/16") copper nickel brake lines and M10x1 fittings for 3/16" line. Made flarings with flaring tool.
This kind of line is easy to work, so bending it under the car is not hard.
Of course this is time consuming job, because it's pretty long brake line and there are lot of holders for it.
Lots of diys found online.

If it's possible you could just replace end of the line. This is what you need:

Just cut the new line to needed length and bend it. Use compression fitting to connect new line to old one.

Are compression fittings safe? I keep hearing that it's a dodgy solution.

No! Not for brake lines. No compression fittings.
You should use a double flare tool, make a brake flare on the shortened line, then use a connector to splice into the new line, also flared, that will carry over to caliper hose.
A double flare tool first plumps the line out, in a bulge, then folds half of the bulge back on itself to form the double flare. Its a two step process. You clamp the line in tool, then press the fitting in that makes the bulge, then press a different fitting that makes the flare.
