The article is devoted to the superconductivity of friction pairs of brake devices, which is possessed by the entire body of the metal friction element and the surface layer of the polymer lining. In them, a special role is played by the so-called thread-like structures in the nodes of the crystal lattices of friction pair materials, which have a reasonably high conductivity due to their low electrical resistance. The use of one-dimensional, two-dimensional, and three-dimensional conductive polymers with different superconductivity efficiencies installed in polymer pads from its downward surface to the advancing one will make it possible to equalize the surface energy load on the arc of the pad’s girth during electrothermal-mechanical friction. The external discreteness of the contacts of the microprotrusions of the brake friction pairs is characterized by internal discrete energy levels, which have an essential feature - they break up into groups representing zones of different widths with unequal mobility of electrons in them. Theoretical and experimental studies have determined that when microprotrusions of friction pairs vibrate, a Cooper pair of electrons breaks with the absorption of an electromagnetic field quantum (photon) and a sound quantum (phonon).
