Brake fluid absorbes moisture. That moisture tends to collect in the brake calipers where it does several bad things....

David, you posted an excellent summary. Thanks! However, I disagree that calipers last the life of the car - after ten or 12 years, they usually go bad.
The owners manual of my 1981 320i specifies that the brake fluid should be changed EVERY year, so the 2-year current recommendation is less meticulous. My 1986 Toyota Camry had no scheduled brake fluid change at all. I asked my mechanic why not, and he replied that most people would not spend the money, so why print it in the book? That sounds like the problem manufacturers have with recommending auto tranny flush. Sometimes they suggest every 50,000 miles, and people complain and ignore it and than say the manufacturer made a crummy transmission when it fails.
