My hubs have self adjusting brakes. We did though readjust them when we had the failure a few years ago.
Self adjusters......
Then is sounds like the one that over wears is over-adjusting (or the others are not adjusting when you brake)
That and along with low voltage/amps on magnets.
Magnets have to grab contact surface in order to engage primary shoe which then rotates and applies secondary shoe. This action also adjusts shoes via cable/lever moving and turning star wheel
If surface is rusted or low voltage/amps to magnets they can't grab
