It's all a matter of opinion...... unless you do seriously hard braking (racing, primarily), there is no detremental brake fluid routine. It's not like oil, coolant, or even trany fluid. if you want to change it, go ahead. It seems like alot of people on here think it's such an important part of mainatining a car. I just have never changed it, and I've driven alot of high and low mileage cars, none of which have never had the fluid changed. And I can tell you that the 1989 Accord I owned had 148,000 miles and the brake pedal felt alot better than the 1990 Chevy Beretta GT I owned with 60,000 miles.
