I'm hoping for a quick answer on this. I'm installing my new stainless brake lines, and need to shorten the lines on the rear housing a couple inches and re-flare them.

Do they need to be single flare 37 degree, or double flare 45 degree flares?

These are stainless hard lines going into the copper end of the rubber hose.

Thanks!

Nevermind, found the answer in the archives!
