Brake fluids can absorb water over time, and you can lose braking power, it is a fact. depending on how hard you drive your car this is more or less likely to happen. My Accord is a DD and rarely sees any hard driving because it handles like the overweight, FWD, understeering pig that it is.
OTOH my Miata's brake system gets a workout quite regularly, and thus will need to be flushed/bled on a regular basis.
Mushy pedal feel usually creeps up on you, and you never realize how bad it was until you bleed/replace the fluid
im gonna have to agree with this guy. Brake fluid does lose its "dry property" over time. Most brake fluids are only really good for about 2-3 years on the regular road. Does it need to be changed? maybe. Most folks don't know how to use their brakes effectively and prolly end up using them too much. As a result, the fluid isn't overly important, because most folks are riding their brakes and not depending on a good solid push from the fluid. Most folks are really negligent too. BTW their is a lil air in your reservoir. As your pads wear down, the level of the fluid drops a lil. Furthermore, do you really trust your master cylinder to be perfectly waterproof from the humidity in the atmosphere?
I have had the fluid changed in my car once when I got SS lines and once about a year ago. Last year when I used ATE super blue, the fresh fluid made a difference in terms of simply giving a solid and more responsive pedal feel. THis stuff is great because I have stood on the brakes from 60-0 a coupla times and there is no fade.
The super blue is cool too cuz it is blue, so when you change fluids you will see the color change as the old is flushed out. BTW they also make a yellow fluid which will be goin in my car next year, so i can tell the difference from the blue stuff.
Many folks that autocross on the weekends will change the fluid that they were using on the street to a fresh batch every race and some will do it between laps. So I really think spending the $20-30 bucks to put fresh fluid in every 2-3 years is not a big deal considering how much people spend on cheap halogen bulbs every six months.
