Motorcycle brake fluid should be replaced every two years or 50,000 kilometers. Introduction to Brake Fluid: Brake fluid, also known as brake oil or hydraulic brake fluid, comes in three types: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when pressure is applied to the liquid, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking systems operate based on this principle. Reasons for Changing Brake Fluid: After being used for a period of time, brake fluid may experience a decrease in boiling point, contamination, and varying degrees of oxidation and deterioration.
