Yes, changing glycol-based brake fluid every 2 years is strongly recommended in the Ann Arbor area. Note: Some German autos use silicone-based brake fluid and have a longer change interval. It is best to check your vehicle owner's manual or contact the service advisors at Stadium Auto Service in Ann Arbor, MI.
Glycol brake fluid is hygroscopic, meaning it absorbs moisture from the air over time, lowering its boiling point and potentially causing corrosion throughout your vehicle's braking system. Brake fluid replacement flushes out contaminated fluid and replenishes the anti-corrosion additives that help protect brake system components.
The intense heat generated during braking, especially common in Ann Arbor's hilly terrain and during Michigan summers when brakes work harder, requires brake fluid to maintain a high boiling point to function safely. When we service vehicles at Stadium Auto Service, we've seen firsthand how degraded brake fluid can lead to reduced braking performance, spongy brake pedals, and costly corrosion damage to brake calipers, master cylinders, ABS components, and brake lines. The brake fluid replacement service is relatively inexpensive compared with repairing or replacing corroded brake components. For Ann Arbor drivers, the 2-year interval is particularly important because our climate's humidity and wide temperature fluctuations accelerate moisture absorption by the brake fluid, making this preventive maintenance a wise investment in your vehicle's safety and reliability.
