How often should brake fluid be replaced in a new car?

[MacAugust]

Brake fluid in a new car should be replaced every two years. If the water content in the brake fluid is 2.5%, replacement may not be necessary. Generally, replacement is considered when the water content exceeds 3%, and it must be replaced if it exceeds 5%. Brake fluid, also known as brake oil, has a replacement cycle related to the car's braking during driving and the vehicle's braking system. Brake fluid has water-absorbing properties, and if not replaced for a long time, the safety factor of driving will decrease. For vehicles used more frequently, the brake oil can be replaced at around 30,000 kilometers; for those used less frequently, the replacement cycle can be extended accordingly, usually around 50,000 to 60,000 kilometers.
