The brake shoes on our other car (Honda) have auto adjusters and, yes, they will drag a bit here and there. But the drag is sooo small I can't see it causing any measurable loss of MPG. If that's what you are after.
My experience is that eliminating the drag from my rear drums made a very noticeable difference in my coast down. It now coasts for ever............... No quantification though.

Brakes are made for one thing: friction. and they are very good at their job. Friction is an ecomodder's #1 enemy. Don't misunderestimate it.
