Parking brake needs constant maintenance

Every other year my parking brake fails inspection. The problem is almost always the parking brake levers and actuators have froze. Typically, I take it apart, clean off any brake dust and rust, add a little antiseize lubricant (Permatex Aluminum), and reinstall. This buys me a year or two before it seizes again. The vehicle gets driven a few times a month but it sits outside. I can hammer on it from the outside and get a few days out of it, but I really hate taking this apart all the time to repair it, it’s time consuming especially with the disc/drum combo. I could replace it, but I’m not sure it would be any different. What advice do you have for solving this (for more than a few years anyway)? Keep in mind I live in a snow belt where they use lots of salt on the roads.
