How many liters of brake fluid should be changed at one time?

[EmeryMarie]

Generally, only 1~2L of brake fluid is needed for replacement. Here is some relevant information about brake fluid: 1. As one of the consumables, brake fluid naturally needs to be replaced regularly. If the water content in the brake fluid exceeds 5%, it should be replaced promptly. 2. Alternatively, brake fluid should generally be replaced every 40,000 kilometers or every 2 years. When replacing, it is essential to use brake fluid of the same grade as the original. If the original vehicle uses DOT4, only DOT4-grade brake fluid can be used. 3. When replacing brake fluid, it's important to pay attention to the replacement cycle, which varies depending on different climate conditions. Additionally, the choice of brake fluid is crucial—brake fluids from different brands should not be mixed.
