When you press on the brake pedal, it touches the floor. Only when you press on it several times does the pedal travel become shorter. What must you do?

In the scenario where the brake pedal sinks to the floor and only becomes more responsive after multiple presses, it indicates a serious issue with the braking system, likely due to air in the brake lines or a brake fluid leak.

The correct actions are to park the car immediately and have the brakes repaired. According to German traffic laws, it is mandatory to ensure that a vehicle's brakes are in proper working condition for safety. Driving with faulty brakes poses a significant risk not only to the driver but also to other road users.

Filling up the brake fluid might seem like a temporary fix, but it does not address the underlying issues that could lead to brake failure. Therefore, both immediate parking and seeking professional repair are essential steps to ensure vehicle safety.
