There are the analysis and estimation of disc brake friction linings deformation value and impact on the friction body (friction lining on steel base) loading given in this article. It allows to modulate the wear of friction lining in the future research. Such friction body construction was analyzed in this research – the friction body and brake lever are linked with a pin, the direction of this pin is perpendicular regarding the vector of the slipping velocity. The research is significant to the joint-stock company 'Jelgava engineering plant' (A/S 'Jelgavas masinbuves rupnica') – they produce brakes with such construction. The theoretical research was done using two methods – solving differential equation for balk with finite length on elastic base (Winkler's method) and the method of finite elements (FEM). After solving the differential equation for balk with finite length on elastic base the author found equations for vertical displacement y, turning angle θ, specific surface pressure p, bending moment M and transversal force Qy of balk in any cross section. The author used the second calculation method (FEM) to test and evaluate the accuracy of the first method (Winkler's method). Calculation with FEM was carried out by computer using software “Cosmosworks”, before it the 3 dimensional friction body model was built in computer software 'Solidworks'.
