Abstract: A method for the production of braking elements for vehicles, in particular brake pads, includes a die forming step by means of fine and/or traditional shearing of a metal support and a molding step upon the metal support of a block of friction material. The friction material is selected from the group of asbestos free materials, while the metal plate is made of an aluminum alloy selected from the group consisting of aluminum alloys subjected to precipitation hardening (age-hardening alloys) and is made from the fine and/or traditional shearing of a metal sheet when the alloy is in a solubilized state. The alloy is not age hardened until a friction material baking step in order to gain the mechanical properties needed for its operation.

Abstract: A method and system for powder coating non electrically conductive elements, preferably brake pads. A pre-treatment station is upstream of an electrostatic powder coating deposition station and a baking station for melting and polymerizing the powder coating in order to form a coating layer on a surface to be coated. The pre-treatment station causes the elements to be coated to conduct electrically by uniformly wetting said elements by means of creating poorly mineralized water covalent bonds on at least one surface to be coated, in an amount aimed at producing a measurable weight increase in the non electrically conductive elements, which then causes them to conduct electrically. The water adsorbed and/or deposited is subsequently eliminated within the baking station.

Abstract: A friction material, such as those belonging to the NAO or LS classes. The friction material is substantially free from copper and includes non-spherical particles in the form of powders and/or fibers each constituted by a preferably ferrous metallic core and by an at least partial coating of core formed at least partially or totally by tin and/or tin compounds, such as intermetallic Fe—Sn compounds.

Abstract: Methods and devices for estimating a residual torque between the braked (e.g., brake disk or drum) and braking elements (e.g., support plate or friction block) of a vehicle based on acquired and reference temperatures, where the reference temperature can be calculated using an N-dimensional calculation model with an N-dimensional vector of input variables, and where said N-dimensional calculation model can be an analytical or experimental characterization of the thermal behavior of the brake.
