Do You Guys Just Leave The Auto Parking Brake Feature On In Winter?

I'm sorry if this is silly question. I live in New England and park outside. During the winter, I turn off my auto side mirrors because I heard snow/rain can freeze the them into place when it's cold enough. I've heard the parking brake can also be frozen in place if you drive in wet/snowy conditions and then it gets cold enough before things can dry out. What's a good policy?
