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

Ensuring that the brake fluid is changed regularly is crucial for several reasons. Firstly, consistent maintenance of the brake fluid plays a key role in maintaining the functionality of the braking system, especially under heavy braking conditions. This ensures that the vehicle can stop safely when necessary.

Secondly, brake fluid absorbs moisture over time. If the moisture content exceeds the permitted level, it can lead to a reduction in the boiling point of the brake fluid. This can cause the fluid to vaporize under high temperatures, leading to brake failure. Therefore, monitoring and changing the fluid keeps the moisture content within safe limits.

Lastly, regular changes of brake fluid help prevent corrosion and damage to vital components of the braking system, such as brake calipers and master cylinders. Rust and other contaminants can accumulate if the fluid is not changed, potentially leading to costly repairs and compromised safety.

In the context of German traffic regulations, ensuring your vehicle’s brake system is in optimal condition is essential for road safety, and failure to do so can lead to penalties or repercussions during vehicle inspections.
