A multi-disk brake assembly includes a static structure defining a plurality of slots, a plurality of disks including stator disks that are supported by the static structure and are non-rotatable, and rotor disks that are interleaved with the stator disks and are rotatable, the plurality of disks being axially moveable between an engaged position and a disengaged position, and a dust-collecting receptacle that is attachable to the static structure for securement during an operative state of the multi-disk brake assembly. The dust-collecting receptacle is in fluid communication with the plurality of slots for receiving and trapping dust from the plurality of disks through the plurality of slots. The dust-collecting receptacle is detachable relative to the static structure during a non-operative state of the multi-disk brake assembly.
