Changing brake fluid can be a slippery subject. 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 steep hill when this happens). But, if you're smart, you'll take good care of your brakes. You'll replace the pads and brake discs as needed. Still, when your mechanic recommends that you get your brake system changed, do you think you should you do it or save the cash?


Do it.  Most manufacturers include it in their maintenance schedules. Mercedes-Benz, for example, says brake fluid should be replaced every two years or 20,000 miles, and Volkswagen, Audi, Seat and Skoda say that it should be done on most of its models every two years regardless of mileage. Subaru recommends fresh brake fluid every 30,000 miles. As a guideline replacing your brake fluid every two years should be sufficient to maintain your braking system in tip top condition

What can happen if you don’t replace your brake fluid? Well braking systems aren't indestructible. Even though brake fluid dwells in a sealed system it still can absorb moisture over time. Brake fluid must withstand operating temperatures of up to 230°C but over time absorbs water which boils at 100°C. As the water boils, it turns to compressible vapour which means you won't be able to brake as efficiently. If too much moisture builds up, the brake fluid can boil while you're braking, seriously affecting performance. It can cause the brakes to fail. A spongy feel to the brake pedal shows you this has started to happen. Too much moisture can lead to corrosion in the brake system. Moisture also lowers the boiling temperature of brake fluid, and that can reduce braking effectiveness in repeated hard stops. Parts, like the rubber in the valves in the master cylinder, calipers and wheel cylinders all deteriorate and its the brake fluid that lubricates all these parts. 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 also leads to rust, which leads to more nasty bits in your brake fluid. All this adds up to a braking system with compromised effectiveness and decreased stopping power.

Think of it this way: You wouldn't skip changing your car's engine oil, right? It's the lifeblood of your engine, and when it gets contaminated by impurities, you put the entire engine at risk. It's the same with brake fluid. Let it get dirty and you won't be able to stop as well. Replacing brake fluid is cheaper than replacing brake lines or a master cylinder that has corroded.
