Abstract: Various residual braking torque indication devices, systems, and methods are described. The devices, systems, and methods can include a sensorized brake pad. An output signal of the sensorized brake pad can be processed to provide an indication of a residual braking torque. The residual braking torque indicator can be calibrated to reference data to provide an actual measurement of the residual braking torque.

Abstract: Method for manufacturing an asbestos-free friction material having as component materials inorganic and/or organic and/or metallic fibers, at least one organic binder, at least one friction modifier or lubricant and at least a filler or abrasive. The raw components of the friction material are mixed together to obtain a raw mixture which is then molded to obtain a block or layer of friction material. The mixing step includes a first step of hot blending of at least part of the organic binder with at least part of the other components of the friction material by a rolling mill blender that is open to atmospheric pressure at a temperature lower than the polymerization temperature of the organic binder but greater than or equal to its softening temperature, in order to obtain a semifinished solid product. A second step of grinding the semifinished solid product reduces the product to a powder.

Abstract: A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.
