Refreshing brakes - what should I look at?

Yeah... the lines were kinda decided for me when I broke the lines off at the connections. I soaked them in penetrant and used a flare wrench... the nuts came loose, but then snapped the line. Oh well. We are redoing the engine bay, so there is nothing in there right now, and the stainless will look good.

Need to do something with the master cylinder for sure... its crusty as hell and had a lot of crud in it. For the money, I'll probably just replace it. Manual brakes, so it is a 1" master cylinder. I might like to go to a 15/16" if I can find one for reasonable money.
