A device (100) for the thermal treatment of friction lining surfaces (19) (scorching) is characterized in that at least one infrared light source is placed in the heating station (10) for heating the friction lining surfaces. Short-wave infrared light of approximately 780 to 1400 nm with a maximum at 1200 nm is preferably used. A suction bell (11) and a fan (12) for removing the decomposition gas are above the heating station (10). The irradiation can take place in depression or in special chemical atmospheres. An infrared thermometer (20) supervises the temperature of the friction lining surfaces (19) and eventually causes an elimination (14) of parts. A cooling station (17) is following the heating station (10).
