The temperature control of automotive brake discs during operation is a difficult process because they have shiny metallic surfaces moving rotational contact with fixed brake pads and different temperature gradients. The instrument used for measuring the temperature, in this case is the thermal camera, but requires precise calibration for the emissivity of the material being analyzed and the influence of environment. The study refers to changes depending on the temperature of thermal emissivity of the material disc brake car, both in static and in dynamic regime and determining analytical relationships to estimate this variation acceptable accuracy.

Keywords: brake disc, emissivity variation, reflectivity, temperature.
