The aircraft brake retention mechanism (40) comprises a retractable mechanism (41) having an enlarged circular head (42), and a threaded shaft (43) received threadedly in an end part (50) biased by a resilient mechanism (60). The head (42), shaft (43), end part (50) and resilient mechanism (60) are received within a radial opening (33) of a piston housing (30), with the end part (50) extending through the radial opening (33) and into abutting engagement with a flange (13A) of the axle (13). The piston housing (30) is connected fixedly with a torque tube (20) so that the piston housing (30)/torque tube (20) and associated brake discs (34, 36) are retained axially by the axle flange (13A) which is captured axially between the end part (50) and torque tube (20). The retractable mechanism (41) may be retracted manually and rotated to engage a surface (37A) of the piston housing (30) and be retained in the retracted position, so that the brake assembly (10) may be disengaged from the axle (13).
