Born from years of research and brake dyno testing, the Twin Powerâ„¢ X-Stop Sintered Brake Pads benefit from the latest in design and manufacturing technologies. Crafted from a select blend of metallic and compound materials fused together resulting in greater heat resistance, longer pad life and increased performance over organic pads. Engineered for heavy-duty use, sintered pads are standard on most machines, giving you stopping power when you need it.
