Why must you ensure the brake fluid is changed regularly in accordance with the vehicle manufacturer's instructions?

Regularly changing brake fluid is crucial for several reasons. First, it helps ensure that the braking system functions properly, particularly when under high load, which can occur during emergency braking or when carrying heavy loads. A well-functioning braking system is essential for maintaining safety on the road.

Second, over time, brake fluid can absorb moisture from the air. If the water content exceeds the permissible level, it can lead to brake failure because water has a lower boiling point than brake fluid. This moisture can cause the brake fluid to vaporize under high temperatures, resulting in a loss of braking pressure.

Finally, changing the brake fluid helps prevent damage to the components of the braking system. Old or contaminated fluid can corrode metal parts and degrade rubber seals, leading to costly repairs and potential safety hazards.

In accordance with German traffic regulations, maintaining the vehicle's braking system is a fundamental responsibility of the driver, and regular fluid changes align with the manufacturer's maintenance guidelines. This combination of reasons underscores the importance of adhering to the specified maintenance schedule for brake fluid.
