Ferro-Carbon is a unique, high-tech family of friction materials developed and manufactured by Hawk Brake for the racing community. Hawk Pads do not require an extensive "bedding-in" procedure. Keep in mind however, that all disc brake pads require a short period of bedding-in before being used to the maximum of their potential.
