BMW says every 2 years and not miles for brake fluid flushes because the reason it needs to be changed is because the fluid absorbs moisture over time, which is not really mileage dependent. It's a fairly cheap service, but you can buy a small tool that reads the moisture content so you can do it as needed and not on a rigid schedule.
