Brake line removal/repair/replacement (something?) help

[rhock99 at epix.net (Ryan H)]

My rearmost hard brake lines are leaking due to rust, so since I had to drop the rear beam anyway, I figured I'd replace the rubber lines with SS.  Well, I can't disconnect the rubber line at the front and it's looking pretty rusted on the hard line near the connection anyway, so is there any way I can cut a section of the hard brake line and put in a new section?  Like an extension of sorts.  I keep thinking, ok just put on a female end and flare the line, but in my mind two flares just don't seem to match up... any ideas?
