Abstract: Brake pads are prepared using a LS (Low Steel) or NAO (Non-Asbestos Organics) type friction material formulation and at least one friction surface of a brake disc intended to cooperate in use with a brake pad that is coated with an anti-wear and anti-corrosion coating with adequate plasticity in order to have a reduced propensity to form micro-cracks under conditions of tribo-mechanical stress, chosen from the amongst the group consisting in: particles of chromium carbide (Cr3C2) dispersed within a metallic matrix consisting of an alloy of NiCr; particles of a combination of several metallic materials in order to create a metallic compound consisting of an alloy of FeNiCrMoSiC (iron-nickel-chromium-molybdenum-silicon-carbon).

Abstract: Brake pads are prepared using a formulation of friction material of the copper-free type (Low-Steel or Organic Non-Asbestos) and at least one friction surface of a brake disc, which is intended to cooperate with the brake pad, is covered with an anti-wear and anti-corrosion coating consisting of a surface layer of chromium carbide particles (Cr3C2) dispersed in a metallic matrix consisting of a NiCr alloy, and coupled to a second layer consisting of selected combinations of metallic materials, chosen from the group consisting of: Cr3C2-high density NiCr, NiAl alloys, FeNiCrMoSiC alloys, metallic nickel, NiCr alloys, and/or any combination of the above.
