The OTC Brake Pad Gauge, No. 6596, helps a technician quickly and easily identify brake pad life on in-board or out-board pads without removing any vehicle components. Using a pencil-style gauge, technicians can check wear on brake pads while performing other service on a vehicle, with a red-yellow-green indicator to explain recommendations to a customer. Green means pads are OK, yellow indicates they will need replacement soon while red suggests immediate replacement. A clear, color-coded indicator allows customer and technician alike to assess brake pad life, giving a recommendation for the future and helping a customer have confidence in their vehicle and technician. The Brake Pad Gauge turns a potentially labor-intensive job into something as quick as checking tire pressure, saving time and money while confidently providing a customer an update on a vital vehicle system.
