<p>A disc brake comprising a rotor and a stator wherein the rotor and/or the stator includes a mounting member provided with a friction lining formed at least in part by a plurality of graphite plates, each plate having two flat side faces and a peripheral surface which is perpendicular to the two flat side faces, each plate being received in a recess in a side face of the mounting member, each recess having a flat bottom surface and being of a depth less than the thickness of the plate, the side wall of the recess being parallel to the peripheral surface of the plate and spaced from the peripheral surface of the plate by a distance greater than that necessary to permit thermal expansion and contraction between the mounting member and the plate and means for retaining each plate in its recess, wherein the graphite plates of one of the rotor and the stator are formed of polycrystalline graphite and the other of the rotor and the stator is formed and/or has graphite plates formed of structural graphite. The means for retaining each plate in its recess may comprise a countersunk rivet extending from the bottom of the recess and passing through the plate with a radial clearance greater than said spacing. The mounting member of that one of the rotor and stator having graphite plates of polycrystalline graphite can be formed of steel, titanium, beryllium, or alloys thereof or structural graphite or a complex substance containing same. The mounting member with graphite plates of structural graphite can itself be formed of structural graphite,</p> |
