Replacement Criteria for Sharan Brake Fluid?
1 Answers
Brake fluid does not have a fixed replacement standard; typically, the moisture content of the brake fluid serves as the basis for replacement. This is because moisture lowers the boiling point of the brake fluid, causing vapor to form in the lines during braking, ultimately leading to ineffective travel and making the brake pedal feel soft, thereby affecting braking performance. Most manufacturers recommend replacing the brake fluid every two years or 40,000 kilometers, although this standard is somewhat conservative. Below is additional information: Reasons for replacement every two years or 40,000 kilometers: Manufacturers recommend replacing brake fluid at intervals of two years or 40,000 kilometers as a general consideration, as they cannot precisely monitor the actual condition of the brake fluid in every vehicle sold. For instance, some vehicles are used frequently, subjected to heavy braking loads, or operate in humid environments, while others are used sparingly, experience light braking loads, or are in dry environments. Therefore, to strike a balanced approach, the recommendation of two years or 40,000 kilometers was established. If the vehicle is primarily used for commuting with little aggressive driving, there is no need to adhere strictly to the manufacturer's recommendation; simply refer to the moisture content. Brake fluid replacement criteria: When the moisture content of the brake fluid reaches 3.5%, it can be replaced. Of course, if the driving environment is merely congested urban traffic, delaying replacement slightly is acceptable. In congested urban conditions with low average speeds, frequent braking does not generate excessive heat, so replacement within a 4% moisture content is sufficient.
