Rednesss, Brake fluid won't dissolve teflon tape. In hydraulic systems it is recommended that liquid thread sealers be used because of the chance of a piece of tape getting lodged in an orfice. Being a brake system is basically a hydraulic system I would treat it the same way.
Lot's of people have used teflon tape on brake systems with no ill effects, I was one of them until I went to hydraulic design and installation training course. I now do not use telflon tape only because of the training. I don't even use teflon tape on my fuel systems.
Jeff you did a fine job and looks great. Were did you get the green colored steel lines? The parts store I get my steel lines are a silver/zinc color.
