Which condition would indicate a brake pedal pad needs to be replaced?

The need to replace a brake pedal pad is primarily determined by the extent of wear it experiences during its lifespan. When the pad exhibits excessive wear that exposes the metal backing, it indicates that the material has significantly deteriorated, which can lead to reduced braking efficiency and increased risk of damage to other braking components. Brake pads are designed to provide friction against the brake rotor, and if they are worn down to the metal, it compromises their ability to function effectively.

Other conditions such as slight wear, no signs of wear, or normal pad firmness do not warrant immediate replacement since they do not pose an immediate risk to vehicle safety or performance. Excessive wear is a clear signal that action should be taken to ensure that the braking system remains reliable and safe.
