How often should BMW brake fluid be changed?

[CarmenDella]

BMW brake fluid typically has a maintenance cycle of 10,000 kilometers, so it needs to be replaced once the mileage reaches this point. Below are the relevant details: 1. Function of brake fluid: Brake fluid evenly transmits pressure to all parts of the hydraulic system, serving as a liquid that transfers pressure and stops wheel rotation. 2. Types of brake fluid: Brake fluid is categorized into three types: alcohol-based, synthetic, and mineral oil-based. 3. Features of brake fluid: Brake fluid ensures timely and accurate power transmission in both high-temperature and cold conditions, effectively stopping wheel rotation. Additionally, qualified brake fluid, despite being a liquid, does not corrode the vehicle's metal or non-metal components and can extend the service life of the brake pump to some extent. 4. Characteristics of brake fluid: Qualified brake fluid has a high boiling point, allowing it to function normally in high-temperature environments. It also has a low freezing point, preventing solidification in cold weather that could render it unusable.
