What is a key indicator of brake failure during inspection?

The presence of a spongy brake feel or excessive pedal travel is a key indicator of potential brake failure during an inspection. This condition often suggests that there may be air in the brake lines, a leak in the hydraulic system, or deterioration of the brake components. When the brake pedal feels spongy, it typically means that the brake system may not be effectively building hydraulic pressure, leading to a delay or weakness in braking performance. Excessive pedal travel indicates that the pedal must be depressed much further than usual for the brakes to engage, which can significantly impair the vehicle's stopping ability and pose a serious safety risk.

While excessive noise during braking might suggest issues such as worn brake pads, it does not directly indicate brake failure. Rapid tire wear can be symptomatic of alignment issues or suspension problems but does not necessarily relate to the braking system's functionality. The absence of warning lights might give an impression of a properly functioning system, but it does not encompass the entire performance of the brakes, especially in cases where mechanical failure is present without triggering warning indicators.
