When is brake fluid typically recommended to be changed?

The recommendation to change brake fluid every two years or as needed is based on the fluid's hygroscopic nature, meaning it can absorb moisture over time. This moisture lowers the boiling point of the fluid, reduces its effectiveness, and can lead to brake fade or failure under extreme conditions. Regularly changing the brake fluid helps maintain optimal braking performance and extends the life of the brake system components by preventing corrosion that can occur in the presence of moisture.

While some manufacturers may specify different intervals based on their vehicles or systems, generally, a two-year change interval is a widely accepted guideline in the automotive industry to ensure safe and reliable braking performance. This periodic replacement allows the brake system to function effectively and helps identify any issues before they become serious problems.
