Antimony in brake pads-a carcinogenic component?

Hence, the use of Sb in friction material should be suspected to pose a human cancer risk and be deterred. To design healthy and environmentally sound alternatives, we propose to apply the Intelligent Product System that distinguishes products of consumption and products of service. Brake pads are true products of consumption, because they are released to biological cycles, and should thus consist of materials with positively defined health and environmental properties.
