They are assembled with DFC premium rubber-steel-rubber shims for improved NVH (noise/vibration/harshness) characteristics, and they are scorched to get rid of extra resins and gases during the manufacturing process for improved stopping power, faster break-in time, and superior durability. Each DFC 5000 Advanced ceramic brake pad is also positive mold, chamfered, and slotted (where applicable) to promote consistent friction material density and reduce noise when braking. And since it is an eco-friendly, asbestos-free brake pad, it is cleaner for the environment as well as for the wheels and other brake components, leading to a longer lifespan and virtually dust-free braking.
