When it comes to brake pads, ceramics may be bringing the reign of the semi-metallic pad to a screeching halt. According to the brake pad experts, ceramic materials are a good choice for brake linings because they have more stable and predictable friction characteristics than most semi-metallic materials. Because the coefficient of friction doesn't drop off as quickly as semi-metallics, ceramics provide a consistent pedal feel that is the same whether the pads are hot or cold. There is a lot less NVH (noise, vibration & harshness) with ceramics, which makes the brakes a lot quieter. Ceramics also give off less dust. Or so it seems. The dust is lighter in color and doesn't show up on your wheels.
