Abstract: An aircraft braking system for a main undercarriage or undercarriages incorporates at least two brakes, which may be carbon type brakes, and a control unit for selectively disabling at least one brake during taxiing only, the control unit being arranged to ensure that the disabling of the brake or brakes does not affect the directional stability of the aircraft when the braking system is operated.

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.
