WIPO Patent Application WO/2014/090763
Kind Code:

Abstract:
The invention proposes an arrangement containing a brake piston (16) for the operation of at least one disk brake pad and a nut-and-screw unit (44, 46) for producing an axial thrust, from the rear to the front, of the piston (16) containing a nut (46) that is arranged in the interior (33) of the piston (16), in relation to which it is secured in order to prevent rotation, and inside which it is mounted so as to slide axially, the front axial end face (52) of which interacts with an internal section (54) facing the front wall of the piston (16) in order to push the piston axially (16) towards the front when the screw (44) is driven in a rotating manner in the direction of unscrewing, and a screw (44) containing a front section screwed into the nut (46), an intermediate radial flange and a rear section (66), characterized in that the piston (16) and the screw (44) contain means of centering (90, 92) that interact with one another when the screw (44) is in a predetermined front axial mounting position in relation to the piston (16) in order to center the rear section (66) of the screw (44) radially in relation to the piston (16).
