How often should the brake fluid be changed in a Buick Regal?
2 Answers
Buick Regal brake fluid is generally changed every two years. Here is a brief introduction: 1. The replacement interval can vary depending on the vehicle's usage conditions, and it is also related to the brand of brake fluid and the vehicle model. 2. The brake fluid specification for the Buick Regal is DOT4. Below are the consequences of not changing the brake fluid in a Buick Regal for an extended period: Although the replacement cycle for brake fluid is relatively long, failure to change it in a timely manner can lead to the brake fluid becoming turbid, a decrease in boiling point, and reduced effectiveness. Over time, this can damage the entire braking system (repair costs can be as high as thousands of yuan) and even result in brake failure.
For the Buick Regal's brake fluid replacement, you need to refer to the maintenance manual, which clearly states that it should generally be changed every two years or 40,000 kilometers. My car has been running for five years, and I've changed the brake fluid twice during that time. Honestly, you can't cut corners with brake fluid. Over time, it deteriorates and absorbs moisture, making the brake pedal feel spongy and unresponsive when pressed. This is especially concerning during long trips or in high-temperature summer traffic jams when the brake fluid's boiling point drops, leading to annoying vapor lock. Last time I went for maintenance right on schedule, the mechanic used a tester and found the moisture content had exceeded 3%, so we replaced it immediately. If you frequently drive on mountain roads or live in humid areas, it's best to check it ahead of time—safety is no small matter. After the replacement, I noticed a significant improvement in braking responsiveness. I recommend you stick to the maintenance schedule and not delay—spending a little now can prevent big problems later.
