What does a brake pad gauge measure?

A brake pad gauge is a specialized tool designed to measure the remaining thickness of the brake pads in inches. This measurement is crucial because brake pads wear down over time due to friction and heat generated during braking. Knowing the remaining thickness helps assess whether the pads need to be replaced to ensure optimal braking performance and safety. If the pads are worn beyond a certain thickness, they may compromise braking efficiency and increase stopping distances, potentially leading to unsafe driving conditions. The measurement provided by the gauge assists technicians in making informed decisions about maintenance and replacement of brake components, thereby ensuring the vehicle operates safely and effectively.
