I thought I read somewhere that it's bad juju to use your brakes while on a trainer (mag, fluid, etc.). This seems reasonable to me. Is is true?

I'm in the process of sprucing up and old roadie (mid 80's Schwinn LeTour) for trainer use during the upcoming winter. It would save me a bit of time and effort if I could just remove the brakes instead of replacing cables, pads, etc. I have no intention of riding anywhere else but on the trainer.
