Brake linings for modern saloon cars are formulated from asbestos fibres as a reinforcement, phynolic formaldehyde resin as a binder, and different fillers to modify the different properties of the linings. To study the effect of every constituent on the mechanical properties, different formulations were produced with different asbestos-resin content ratio and the mechanical proper-ties, mainly, the ultimate tensile strength, impact strength, hardness, and the compressive strength were measured. Definite dependency of the mechanical properties of such formulations on the asbestos-resin weight ratio was noticed.
