How often should brake fluid be flushed for optimal vehicle maintenance?

Flushing the brake fluid every two years is recommended for optimal vehicle maintenance because brake fluid can absorb moisture from the air over time. This moisture can lead to a decrease in the fluid's boiling point, potentially causing brake fade and insufficient braking performance, particularly during heavy braking conditions. Additionally, water contamination can promote corrosion within the brake system, which can lead to costly repairs and compromised safety.

By scheduling a brake fluid flush every two years, vehicle owners ensure that the brake fluid is replaced with fresh fluid that maintains proper performance characteristics, thereby enhancing the overall safety and reliability of the braking system. Regular maintenance helps prevent brake system failures and extends the life of components such as brake calipers and master cylinders.
