How often should the original brake fluid be replaced?

[OBrandon]

Brake fluid should be replaced every 40,000 kilometers or 3 years. Here are the precautions for brake fluid usage: 1. Do not mix different types or brands of brake fluid. Due to different formulations, mixing brake fluids can cause a decline in performance. 2. Replace if moisture content is high: When brake fluid absorbs moisture or contains impurities, it should be replaced or filtered promptly. Otherwise, it may lead to insufficient braking pressure and affect braking performance. 3. Replace after long-term use: For vehicles that have traveled 40,000 kilometers normally or have used the same brake fluid continuously for over 3 years, the brake fluid can easily deteriorate due to prolonged use and should be replaced in a timely manner.

The replacement interval for brake fluid varies from person to person, but it is generally recommended to change it every two years or approximately every 30,000 kilometers. I personally prioritize safety when driving, as it directly relates to braking performance. Brake fluid absorbs moisture from the air, and over time, its boiling point decreases, which can lead to failure or even bubbling during emergency braking. Once, while driving in the rain, I noticed the brakes felt spongy and immediately went to replace the fluid. I regularly check the brake fluid reservoir level, which is easily visible under the hood. If the level is low or the fluid appears cloudy, take it to a repair shop right away. Regularly replacing brake fluid can extend the lifespan of your braking system and provide peace of mind for you and your family. Follow the maintenance recommendations in your vehicle’s manual—don’t wait until problems arise to regret neglecting it.

Experience tells me that brake fluid must be changed regularly, otherwise the braking response becomes sluggish. Having driven for over a decade, I change it every two years or so. If left too long, the brake fluid absorbs moisture, lowering its boiling point, which may cause failure during high-speed driving or on slopes. I recommend developing a habit of checking whether the fluid level is within the normal range. If the brake pedal feels soft or there are unusual noises, it's likely a fluid issue. It's more convenient to replace it during routine maintenance. Excessive moisture accumulation can corrode system components, increasing repair costs. Safety is no small matter; changing the fluid on time ensures smoother driving.

As a car owner, I would refer to the vehicle manual's recommendations - brake fluid should typically be replaced every 2 years or 30,000 kilometers. Delaying too long can lead to increased moisture content, which affects braking performance. When the color changes in the brake fluid reservoir under the hood, it's time for replacement. Beginners should ideally have technicians test the moisture content during regular maintenance. Failure to replace it may pose risks, so address it promptly to ensure smooth driving.

I find it not difficult to change the brake fluid myself, usually doing it every two years. Open the hood and locate the brake fluid reservoir, then check the fluid level and color change. Brake fluid is highly hygroscopic, and its boiling point decreases over time. You can DIY by extracting the old fluid and adding new fluid to ensure cleanliness. Keep the fluid level within the specified range to avoid air bubbles. Combine this with other checks to make the system more reliable.

Brake fluid replacement is one of the routine maintenance items. It's recommended to replace it every two years or approximately 30,000 kilometers as per the manual. Excessive moisture content can shorten braking distance. I regularly check if the fluid level is normal. I take a glance at the reservoir condition every six months or so. If the fluid becomes cloudy or contains impurities, it should be replaced. Combining this with tire and engine oil maintenance yields better results. Neglecting it may lead to brake failure during emergencies.
