This study is concerned with a thermal analysis of a braking disc surface for a better understanding of the phenomenas occurring during friction. To discriminate thermal and physico-chemical phenomena, measurements of temperature and emissivity fields are essential during a braking test. This measurement is performed based on a bichromatic thermography technique using two Infrared cameras. To follow the evolution of those phenomenas, the cameras are used to observe the same area of the disc
