Why should you regularly apply the brakes with force at standstill?

The selected combination is correct because both points address essential safety checks for the brake system.

1. Checking whether the mechanical transmission and connection components are in functioning order ensures that the entire braking system can respond effectively when needed. This is crucial for safety, as faulty connections can lead to brake failure.

2. Verifying that the hydraulic braking system has no leaks is equally vital. Any leaks can reduce brake pressure, significantly impairing braking performance.

Regularly applying the brakes while standing allows you to check these aspects, ensuring that your vehicle remains safe and compliant with German traffic regulations, which emphasize the importance of vehicle maintenance for road safety.

For future reference, remember that while the deceleration of the brakes is important for performance, it is the functionality and integrity of the braking system that primarily ensures safety and compliance with the laws.
