Wheel cylinder removal

I'm in process of removing the front driver side wheel cylinder from my '66 Barracuda. I'm to the point of removing the flexible brake line. I was able to get the line loose but I can't continue to unscrew the line from the cylinder because the line is fixed at the other end at a bracket and connected to the hard line. Picture attached. I'm not sure how to proceed at this point. Should I be able to detach the hard line from the flexible line at this point? There is also a u-clip that looks like it holds this junction to the bracket. Should I try to free this junction from the bracket before I try to break the connection between the two lines?
Any input would be welcome.
