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. 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.
A disc brake comprising a rotor element and a stator element, one of said elements including a mounting member provided with a friction lining formed at least in part by a plurality of graphite plates, each of said plates having two flat side faces and a peripheral surface which is perpendicular to said two flat side faces, each of said plates being received in a recess provided in a side face of said mounting member, each said recess having a flat bottom surface and being of a depth less than the thickness of said plate, the side wall of said recess being parallel to said peripheral surface of said plate and spaced from said peripheral surface of said plate by a distance greater than that necessary to permit thermal expansion and contraction between said mounting member and said plate means for retaining said plate in said recess, said graphite plates of one of said elements being formed of polycrystalline graphite, the other of said elements being formed as a unitary element of structural graphite.
A disc brake comprising a rotor element and a stator element, each of said elements including a respective mounting member provided with a friction lining formed at least in part by a plurality of graphite plates, each of said plates having two flat side faces, each of said plates being received in a recess provided in a side face of said mounting member, each said recess having a flat bottom surface and being of a depth less than the thickness of said plate, the side wall of said recess being parallel to said peripheral surface of said plate and spaced from said peripheral sruface of said plate by a distance greater than that necessary to permit thermal expansion and contraction between said mounting member and said plate and means for retaining said plate in said recess, said graphite plates of one of said elements being formed of polycrystalline graphite and said graphite plates of the other of said elements being formed of structural graphite.
