How often should the brake fluid in a BMW X1 be changed?
1 Answers
BMW X1 brake fluid replacement interval is every 2 years or 60,000 kilometers. The brake fluid filler port for the BMW X1 is located in the engine compartment and requires removal of the air filter to access. The specification used is DOT4 brake fluid. Reasons for regular brake fluid replacement: Brake fluid directly affects braking performance. Due to weather and external factors, brake fluid absorbs moisture and contaminants, causing it to deteriorate. This leads to insufficient braking force, creating safety hazards. Contaminated brake fluid also causes wear to sealing components in the braking system, shortening the lifespan of brake components, making regular replacement essential. Criteria for determining brake fluid replacement: The sole criterion for determining whether brake fluid needs replacement is its moisture content. When the moisture content in the brake fluid exceeds 5%, the fluid is deemed unusable and requires immediate replacement. If inspection reveals moisture content above 3%, it indicates significant deterioration of the brake fluid. Although it hasn't reached 5% moisture content, drivers should be prepared to replace it as soon as possible.
