Abstract
Friction material is a very important element of disc brakes, because it is directly related to brake performance in such areas as effectiveness, friction stability with various brake conditions, lining life and different kinds of noise and vibration. Although friction material manufacturers have worked to develop many different friction materials, very few studies have been published about the development of friction materials. Therefore knowledge of friction material development is not widespread. The scope of this paper is the basic considerations, studies and experiments which focus on better friction material development.
