A hydraulic motor brake for providing load holding torque to a hydraulic motor and comprising a housing, a plate fixedly mounted within the housing, a piston mounted for bi-directional translation relative to the plate along a longitudinal axis, and a plurality of friction-producing members arranged such that the piston and plate at least partially define a brake release chamber and the piston, normally biased in engagement with the friction-producing members to produce load holding torque, translates away from the plate and disengages from the friction-producing members to stop producing load holding torque in response to pressurized hydraulic fluid being received by the brake release chamber. The hydraulic motor brake further comprises a wear plate with the brake housing and wear plate defining bores arranged in coaxial alignment with threaded bores of the hydraulic motor for detachably attaching the hydraulic motor brake to the hydraulic motor as a self-contained unit.

A wet brake includes a housing, non-rotatable brake discs, rotatable brake discs, a parking lever, a piston, a plate, and a connector. The non-rotatable and the rotatable brake discs are disposed in engagement with the housing and an outer peripheral surface of a rotary shaft, respectively. The piston, the plate, and the rotary shaft are accommodated in the housing. The piston is configured to be pushed by the parking lever toward the non-rotatable and the rotatable brake discs. The plate is in contact with one of the non-rotatable brake discs or one of the rotatable brake discs. The connector is disposed at a position between the piston and the plate. The housing has a recess that is formed in an outer peripheral surface of the housing at a position corresponding to the position of the connector. An outer diameter of the connector is smaller than that of the piston.

The invention relates to a disc brake for an aircraft wheel, comprising friction discs (20,30), including rotor discs and stator discs, a structure comprising a torsion tube (11) on which the discs are fitted, a rear plate (12) which is located at one end of the tube, and a support (13) for braking actuators (14,15) at another end of the tube, the actuators being able to be selectively activated in order to apply a pressing force to the discs. According to the invention, the discs are separated into two groups, including a first group (20) which can be used alone for taxiing braking operations, and a second group (30) which can be used alone or in conjunction with the first group for take-off/landing braking operations.
