I was wondering the same thing every time I read a post on ABS failure, thinking if it gets some use (the ABS system) every week or two, it would be beneficial in keeping the seals, valves, pump etc. "limber".
Not a problem here in the ice covered mondo tundra...it gets a workout in the winter at least.
In the more humid months, I've seen water (I assume) floating on top of the brake fluid in the res. & removed it with a spoon that I bent the handle so it looked like an "L". Then just top it off.(note to self: don't eat cocoa krispies with that spoon)
Probably should do another flush this spring before Moab.![]()
