The article analyzes practical research of even wear of disc brake friction linings. The research was carried out to test the theoretical research regarding providing of even wear changing the pressing force application coordinates. Two kinds of the friction body (friction lining on steel base) construction were tested in experimental work. The friction body and brake lever are linked with a pin. The direction of this pin is perpendicular regarding the vector of slipping velocity in the first kind of the construction and parallel – in the second case. The research is significant to the joint-stock company 'Jelgava engineering plant' (A/S 'Jelgavas masinbuves rupnica') – they produce brakes with such construction. The experimental work was carried out in the brake testing laboratory of this company. The author proved that it is possible to provide even wear of friction lining if the design of the friction body is made so that the resultant force is applied with a definite eccentricity regarding the mass centre of the friction lining. The eccentricity depends on the friction body design and friction material properties.
