If you're like most drivers, you don't think about your brakes until they stop working (and hopefully you're not careening down a mountain road when this happens). But, if you're smart, you'll take good care of your brakes. You'll replace the pads and resurface the rotors as needed. Still, when your mechanic recommends that you get your brake system flushed, do you think you should you do it or save the cash?
Braking systems aren't indestructible. Parts, like the rubber in the valves in the master cylinder, calipers and wheel cylinders deteriorate. All the nasty little bits that flake off end up in your brake fluid. Plus, the fluid itself can get old and worn out. Moisture can also get in the system. That leads to rust, which leads to more nasty bits in your brake fluid. All this adds up to a brake system with compromised effectiveness and decreased stopping power.
A good rule of thumb is to have your brakes flushed about every 30,000 miles. Note that brake flushing and bleeding the brakes are two different procedures. Brake flushing involves removing all the brake fluid from the system and getting all-new, clean fluid inside. Brake bleeding just means removing enough brake fluid to get air bubbles out of the brake lines. So, make sure you get your brakes flushed regularly.
