Abstract: A method of making a brake assembly using recycled friction disks may comprise removing a first friction disk from a worn brake assembly, removing a portion of the first friction disk to reduce a thickness of the first friction disk, and incorporating a previously unused friction disk and the first friction disk into a brake assembly comprising unworn rotor disks made of a first material. The previously unused friction disk and the first friction disk may comprise a second material different from the first material. The thickness of the first friction disk may be different from a thickness of the previously unused friction disk.

Abstract: A wheel assembly includes an inboard wheel portion having a rim and a disk. A radially inward surface of the rim and an inboard surface of the disk define a wheel well cavity configured to house a brake assembly. The wheel assembly also includes a torque bar (e.g., a torque bar of the brake assembly) mounted to the inboard wheel portion. Further, the wheel assembly includes a retainer coupled to the torque bar and disposed radially between the torque bar and the radially inward surface of the rim of the inboard wheel portion. The retainer includes a first end, a second end opposite the first end, and a body extending between the first end and the second end. The body includes opposing longitudinal sides configured to respectively engage and retain a respective heat shield segment of a segmented annular heat shield.

Abstract: Systems disclosed herein may be useful for use in a disk brake system. In this regard, a disk brake system may comprise a stator thickness that is less than 15% greater than an end plate thickness and/or pressure plate thickness. Additionally, a disk brake system may further comprise a combination of split friction disks comprising a damping feature and solid friction disks. These split friction disks and/or solid friction disks may be arranged together in any suitable pattern or position within the disk brake system.

Abstract: A friction device such as an aircraft wheel and brake assembly having a wheel member journaled for rotation on a fixed member, which fixed member supports a torque tube member. A plurality of primary friction disks are carried by splines on the wheel member while a plurality of secondary friction disks are carried by splines on the torque tube member with such secondary disks interleaved with the primary friction disks for axial movement towards one end of the torque tube. An actuator, such as a plurality of pistons, is mounted on the fixed member to urge all the friction disks into frictional engagement with each other and against a stationary disk on the one end of the torque tube. A rigid disk is positioned between the actuator and the pluralities of friction disks, and acts as a pressure plate. The rigid disk may be formed of carbon or ceramic composite material.
