Abstract: Various machines, systems, and methods for generating calibration data for a sensorized brake pad are disclosed. In some embodiments, a system includes a fixture, a brake pad retainer, a pressure plate, an actuator and a controller. The actuator applies a pressure to the sensorized brake pad and signals from the pressure sensors are received. Calibration data is generated based on the signals received from the pressures sensors when the pressure is applied to the sensorized brake pad.

Abstract: Methods and equipment for determining conditions of adhesion between a first and a second mechanical element are disclosed. The mechanical elements are attached respectively to a first and second support, which are immersed in an electrolyte together with a counter-electrode and a reference electrode to form an electrochemical cell. The second mechanical element is a working electrode being connected to an insulated electric wire that is also connected to the counter-electrode. A first uncovered face of the second element is pressed against the first element. A potential is applied to the second element of at least one predetermined value and/or a predetermined electrical current. The method can include detecting the electrical current that is transmitted through the electrolyte as a function of the potential applied and/or the potential that is established as a function of the predetermined current.
