In my experience elevator brakes only get louder as time goes on so don’t expect it to get better. A lot of MRL brakes, the ones that are adjustable anyway, do get considerably quieter when adjusted to the tight side of spec. This is definitely true of Kone MX machines and the Torin machines TK uses. Others though are not field adjustable so all the elevator guy can do is check that they’re within spec with a feeler gauge and if they are, that’s what you get.
