Why Does Brake Fluid Need to Be Replaced?

[DiKylie]

Brake fluid needs to be replaced because: after a certain period of use, the boiling point of brake fluid decreases, it becomes contaminated, and undergoes varying degrees of oxidation and deterioration. Brake fluid absorbs moisture from the air, and the hydraulic braking system must allow the brake fluid to be exposed to the atmosphere to function properly. Over time, the brake fluid absorbs moisture, which turns into bubbles under high temperatures. When bubbles form in the brake fluid lines, braking efficiency decreases. Therefore, brake fluid should be regularly checked for quality and performance based on climate, operating environment, seasonal changes, and working conditions, and replaced on schedule. Brake fluid should generally be replaced every two years or 50,000 kilometers. When selecting brake fluid, different types should not be mixed to avoid chemical reactions that could affect braking performance.
