The aim is to develop a method for ensuring the stability and efficiency of the braking process by differentiating the friction linings of brake pads of pad-type disc braking mechanisms. The research applied differentiation of the interaction time of friction pairs and their area, which provides the highest stability indicators of braking mechanisms. The non-standardized bench equipment developed by the author, as well as segmental braking mechanisms providing differentiation of friction pairs by area were used in the study. A method of designing the resultant braking torque was developed using the relationship between the transverse movement of the pads and the developed braking torque of the friction unit. As a result of bench tests, the stability and fluctuation coefficients of the braking torque of the developed pad-type disc brake mechanisms with six pressing elements increased by 12.2 and 34.9%. These values were obtained as compared to serial brake mechanisms equipped with a monopressing mechanism with a single brake pad. The discrepancies between the simulated and obtained data during the bench test on the stability criteria averaged 5.1 and 6.7% for the stability coefficients and braking torque fluctuations for the three brake mechanism variants under consideration, respectively. Differentiation of pressing elements and segmentation of brake pads has the effect of increasing the stability criteria and braking efficiency for pad-type disc brakes. With the analysis of the dependence of the transverse displacement and the developed braking torque, a guaranteed result on the stability criterion and braking torque fluctuations of pad-type disc brakes was modeled. Based on the conducted bench tests, the model developed for obtaining the resultant braking torque for the braking mechanism with segmental pads can be used for designing friction pairs with the set parameters.
