How often should the brake fluid in a Corolla be replaced?
2 Answers
The brake fluid in a Corolla should be replaced every 40,000 kilometers, but this interval can vary depending on usage. The official recommended replacement intervals for brake fluid differ among various car brands, which is related to the brand of brake fluid and the specific vehicle model. Generally, it is recommended to replace the brake fluid every 40,000 kilometers or every 3 years. The Corolla is a compact car produced by FAW Toyota, featuring a 4-door, 5-seat sedan body structure. Its dimensions are 4635mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm. The suspension system combines a MacPherson strut independent front suspension with an E-type multi-link independent rear suspension.
I previously drove a Corolla, and my experience with changing brake fluid is that it's recommended to replace it every two years or after reaching 40,000 kilometers. Why change it? Over time, brake fluid absorbs moisture from the air, which affects braking response and reduces braking force—especially noticeable during rainy days or emergency braking. I once delayed changing it for three years and felt the brakes were soft and less responsive, so I quickly went to a repair shop. The Corolla's manual also recommends this interval, but it depends on your driving habits—if you often drive in congested city traffic or brake frequently on highways, changing it more often is better. During inspection, you can use specialized tools to test moisture content or check if the fluid is cloudy or dark. Regular replacement ensures safety and saves on repair costs—don't underestimate this small task.
