The invention relates to a disc brake for an aircraft wheel, comprising friction discs (), including rotor discs and stator discs, a structure comprising a torsion tube () on which the discs are fitted, a rear plate () which is located at one end of the tube, and a support () for braking actuators () 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 () which can be used alone for taxiing braking operations, and a second group () which can be used alone or in conjunction with the first group for take-off/landing braking operations.

Disc brake for an aircraft wheel

A method for the reconditioning and use of brake discs of the rear stator type with studs. The method includes the steps of using a first disc () during a first life, using a second disc () during a first life, after the first life of the first disc and the first life of the second disc, machining a friction surface on one of the discs and a rear surface on the other of the discs so that one of the surfaces has at least one shoulder () and the other of the surfaces has at least one notch (). Finally, the first disc is nested in the second disc such that the notch and the shoulder cooperate so as to center the discs.

Method for the reconditioning and use of brake discs of the rear stator type with studs, assembled disc and corresponding stack of discs

The invention relates to a method of using and renovating a brake disk (), the method comprising steps of using the disk in a plurality of lives and compensating for a reduction in the thickness of the disk after each life by assembling the disk with a complementary portion or by associating the disk with another disk of rotor or stator type if the disk is itself respectively of stator or rotor type.
