Disk brake mechanisms are widely used in automobile construction at present, their major advantage being high stability. With the brakes stability depending, to a great extent, on the temperature mode, it is of practical importance to do some research into the latter. Wide application of computing thermal physics in the field of bearing technology based on modem thermal models and the means of their solution including information and software, made it possible to investigate these processes in more detail. The paper presents the results of investigation into variable temperature fields in disk brakes obtained by computer simulation with the use of invertion metod. It is shown that the temperature difference between the disk surface under the lining and the surface freed from under it is only 5.8°C, the fact that proves that the process is very short and has no essential effect on the disk cooling per a wheel rotation. The processes of emergency braking affecting temperature stresses in a disk have also been investigated.
