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

The correct combination of answers emphasizes the importance of ensuring the proper functioning of the vehicle's braking system. The first point specifically checks whether the mechanical transmission and connection components are operational, which is crucial because any malfunction could lead to brake failure. The second point addresses the need to verify that the hydraulic braking system is leak-free, as any leaks can significantly impair braking performance, endangering safety.

It is vital to regularly apply the brakes forcefully while at a standstill to conduct these checks effectively. This practice helps confirm that the braking system responds correctly and that both the mechanical and hydraulic components are in proper working order. According to German traffic regulations, maintaining the reliability of the braking system is not only a matter of vehicle maintenance but also a legal requirement to ensure road safety.
