Why Mileage has Nothing to do with Flushing Your Brakes
How often should you flush your brakes? That depends. Every car manufacturer has its own recommendation, and even that is an educated guess at best. Chevy says every 45,000 miles. Honda says 3 years, regardless of mileage. Mercedes? Every two years or 20,000 miles. Some people will even tell you never. Since brake fluid lives in an enclosed system, it can last for years. Problems result, however, when that system isn’t as enclosed as you think. Hoses and attachments wear down over time, which can cause water and other contaminants to leak into the system. What you really need to do is have your brake fluid inspected from time to time. That’s the best way to see if you need a flush service. Mileage might as well be irrelevant.
