The expert technicians at AAMCO Phoenix, AZ (Laveen) recommend replacing the fluid as a preventive maintenance service, every two years or 24,000 miles. That's because brake fluids absorb moisture over time, which could mean your brakes perform less well when you need them the most-during hard braking.
The brake fluid level should be checked periodically, preferably with every oil change. Check your owners manual to determine the recommended interval for changing the brake fluid, or bring your vehicle to AAMCO Phoenix, AZ (Laveen) to have a complete brake inspection. You'll also get the AAMCO 36-Step Vehicle Courtesy Check® to ensure all of the major systems in your vehicle are in good working order.
