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?

You answered correctly because when the brake pedal touches the floor initially, it indicates a serious brake problem. Pressing the pedal several times causing shorter pedal travel suggests air could be in the brake lines or a leak is present, making braking unreliable. According to German traffic rules, you must park the car immediately to avoid danger, as continuing to drive is unsafe. Then, the brakes need to be repaired by a professional to restore proper braking function. Simply filling up brake fluid is not enough, because the issue might be mechanical or due to air in the system, which requires proper diagnosis and repair. This procedure ensures your vehicle remains safe to drive.
