Abstract
A vehicular disc brake rotor is provided with a cast-iron base, a nitrogen diffusion layer formed on the cast-iron base, a nitrogen compound layer formed on the nitrogen diffusion layer, and an iron oxide layer including FeOand formed on the nitrogen compound layer. In a burnish and a first re-burnish of a 'Passenger car-Braking device-Dynamometer test procedures' (which is based on JASO C 406:2000), a change ratio of a frictional coefficient between the burnish and the first re-burnish is 10% or less.
