The disclosed compositions of the friction material are believed to be more environment-friendly than conventional compositions. However, the substantial elimination of elemental metals, metal alloys, and antimony trisulfide from the disclosed compositions is performed in a manner that does not appear to substantially impact the friction performance and noise behavior of the corresponding brake components. Moreover, it is believed that at least some of the disclosed compositions increase the useful lifespan of the brake components and reduce wear of the rotors. The longer brake-components lifespan and lower rotor wear provide additional benefits in terms of reducing non-exhaust-related vehicle emissions, which further alleviates the environmental impact of traffic emissions.
