Abstract: The invention relates to a brake actuator for an aircraft hydraulic brake, which is intended to be added into one of the cavities of a brake ring, the actuator comprising: a liner (1) designed to be housed sealingly in the cavity of the ring; a piston (3) mounted to slide sealingly in the liner along an axis of sliding so as to apply a braking force when a fluid is introduced under pressure into the cavity; a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of a mobile stop (11; 111) that can be moved forward by the piston as a braking force is applied; an elastic return member (18) returning the piston towards the retracted position bearing against the mobile stop; according to the invention, the mobile stop is associated with a notched indexing member (13) allowing the mobile stop to move under the thrust of the piston, but preventing any return motion of the mobile stop with respect to the liner.
