ABSTRACT:
A multi-disc brake includes a plurality of stator discs, a plurality of rotor discs interleaved with the stator discs, a torque tube relative to which stator discs are axially slidably keyed, brake-actuating thrust members for applying an axial thrust to an end stator disc and a reaction member which provides an abutment for the other end stator disc. This other end stator disc includes an element of friction material having a first face which engages a rotor disc for dissipation of energy when axial thrust is applied to the assembly of rotor and stator discs and a second face supported by a substantially rigid backing member. The backing member is supported by the torque tube in an arrangement which prevents rotation of the backing member relative to the torque tube, and the backing member also includes location member which extends axially from that face of the backing member which supports the stator disc friction element. A radially outer region of the stator disc friction element includes relieved regions slots for example, circumferentially spaced relative to the longitudinal axis of the torque tube. The location member is engaged in the relieved regions so that torque load applied to the stator friction element is transmitted to the torque tube.
