What are the effects of not changing brake fluid on a car?

[HannahLee]

It will directly affect the dry and wet boiling points of the brake fluid, not only making it prone to vaporization and causing vapor lock, which leads to delayed braking or even brake failure, but also affecting the stability of the brake fluid. Brake fluid performance: Brake fluid, also known as hydraulic brake fluid or mineral oil brake fluid, has properties such as oxidation stability, anti-foaming, anti-rubber swelling, and anti-rust. Brake fluid replacement cycle: The replacement cycle is related to the braking during driving and the vehicle's braking system. Brake fluid has water-absorbing characteristics, and if not replaced for a long time, the safety factor of driving will be reduced. If the vehicle is used frequently, the brake fluid can be replaced at around 30,000 kilometers; if used less frequently, the replacement cycle can be extended accordingly, generally around 50,000 to 60,000 kilometers.
