Teflon tape is ok if used properly. Do not put any on the last 2 threads of the fitting, it will sluff off and get into the system.
I work for a hydraulic cylinder mfg. and we have to be very carefull in training new people. Any threads of teflon can come off and get on the seats of valves within a hydraulic system. As a side note, there was a service bulletin that came out years ago about using rtv in assembling engines or replacing components. There were instances of globs of rtv comming loose internally and clogging oil systems. I only use permatex brush in can aviation gasket sealer and then sparingly.

I cannot visualize this. It sounds sort of like the Hayes setup, but they don't have calipers. What kind of brakes are they? How about posting a photo? The short answer, though is, if it is a pipe (tapered) thread, then any good quality thread dope will work.
