I wish I had photographic evidence, but I also once had someone try to return brake pads for being defective. He told me a store about how he'd installed the pads and nearly had an accident pulling out of his driveway. Then he opened the box and showed me the "defective" brake pads. He'd installed them backwards (friction material facing the piston instead of the rotor). The pad material had a fairly neat circle cut into it where he'd jammed on the brakes with all of his might in a car with power brakes.
