Abstract: A vehicle braking unit comprising a support designed to be positioned in use close to an element to be braked, braking elements which are carried in a movable way by the support, actuation elements which are carried by the support for pushing the braking elements against the element to be braked and first and second guide surfaces that are integral, respectively, to the braking elements and to the support, and that cooperate together to guide and support the braking elements when they are moved towards the element to be braked by the activation of the actuation elements; the first and/or the second guide surfaces are covered by a sliding coating consisting of a polymeric resin layer with solid lubricants and/or anti-friction materials being dispersed therein, that has been cured at a temperature greater than 300° C.

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.
