Correlation of Vehicle, Dynamometer and Other Laboratory Tests for Brake Friction Materials

The frictional properties of brake lining materials are greatly influenced by the manner in which they are used. Test procedures designed to measure the coefficient of friction of these materials can likewise produce widely differing results depending on the type of test conducted. This paper presents data illustrating the performance correlation of three commercially available brake lining materials when subjected to vehicle tests and some of the more commonly used laboratory test procedures.
