What does excessive brake pedal travel indicate?

Excessive brake pedal travel suggests that there may be a potential issue with the braking system. When the brake pedal travels further than normal before engaging the brakes, it can indicate several underlying problems. These might include air in the brake lines, which can compress more than fluid, resulting in a spongy or overly long pedal feel. It could also signify a fluid leak, low brake fluid levels, or worn brake components, such as brake pads or rotors.

Understanding this symptom is critical for vehicle safety, as it prompts the need for inspection and potential repair of the braking system to ensure it functions effectively when stopping the vehicle. While the other options touch on critical aspects of vehicle maintenance and operation, they do not directly relate to the specific problem indicated by excessive brake pedal travel.
