This article presents selected issues related to the selection methodology of the brake linings during the research process. It is a very important issue due to effect on the vehicle safety. Safety concerns are applicable to both road/track vehicles and aircraft. Scientific institutions and research centers make continuous efforts in order to improve brake lining materials and full-scale brakes. Analytical prediction of the friction material properties and behavior is not accurate enough due to complexity of the physical phenomena. Analysis of the friction materials is difficult due to scarce of data given by the manufacturers. Every friction material needs to be tested in order to prove its properties. First stage of the selection is the tests made in laboratory using both model and full-scale techniques. Because of the laboratory tests, following parameters are obtained: weight and geometrical brake wear, braking torque, friction coefficient and brake temperature. All of these factors must be taken into account for linings selection and design a prototype of the brake. Selection of the friction material can be performed in consideration of various requirements of the brake system users and law defined factors. Authors of the paper base on the extensive experience of the Institute of Aviation, Landing Gear Laboratory tests of brake linings.
