Abstract: A brake actuator for an aircraft hydraulic brake, insertable in a cavity of a brake ring. The actuator comprises 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 (X) so as to apply a braking force when a fluid is introduced under pressure into the cavity, and a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of mobile stop (11) that can be moved forward by the piston as a braking force is applied. An elastic return member (16) returns the piston towards the position of retreat bearing against the mobile stop. The wear compensation device extends between the liner and the piston, downstream of a seal extending between the liner and the piston so as not to be bathed in the fluid in the cavity, the stop being held still by friction on the liner.
