When inspecting brake pads, focusing on thickness and any uneven surfaces is crucial for several reasons. The thickness of brake pads directly relates to their effectiveness; as brake pads wear down, their ability to provide stopping power diminishes. If the pads are too thin, they may not provide adequate friction, leading to longer stopping distances or even brake failure.

Uneven surfaces are equally important to assess. If a brake pad has uneven wear, it can indicate issues such as misalignment of the caliper, problems with the rotor, or improper installation. This can lead to poor braking performance, increased vibration during braking, and accelerated wear of both the pads and rotors.

While aspects like color variation and rust may sometimes provide insights regarding the condition, they are not as critical as the actual physical dimensions and wear patterns of the brake pads. Similarly, weight and elasticity can be indicators of the material type but do not directly affect performance in the same way that thickness and surface condition do. Lastly, size and brand compatibility are important for installation, but they don't provide information about the condition of the pads themselves at the time of inspection.
