What do the terms dry boiling point and wet boiling point of brake fluid mean?

[AdalineLynn]

Brake fluid dry boiling point refers to the boiling point when the fluid is freshly added to the brake system from a sealed container; wet boiling point indicates the boiling point after 2 years of use when the fluid contains 3.5% water. Below are precautions for brake fluid usage: 1. Do not mix: Avoid mixing different types or brands of brake fluid. Due to differing formulations, mixing can degrade the fluid's performance indicators. 2. Moisture or contaminant absorption: When brake fluid absorbs water or contains impurities, it should be promptly replaced or filtered, otherwise it may lead to insufficient braking pressure and affect braking performance. 3. Replacement: For vehicles driven normally for 40,000 km or when brake fluid has been in continuous use for over 2 years, the fluid is prone to deterioration due to prolonged use and should be replaced promptly.
