ABSTRACT:
The invention relates to a disc-brake motor subassembly comprising at least one piston (10), which can be controlled by a mechanical subassembly having first and second plates (40, 48), one of which is actuated in rotation, these two plates bearing mutually faced indentations (54, 56) in which is accommodated at least one ball (52), the indentations being provided in the axial direction of the plates with a slope which allows the conversion of the rotation of a first plate into axial displacement of the second plate in order to control the piston (10). According to the invention, in the course of the rotation the ball (52) follows a trajectory, the distance of each of the points of which from the axis of the plates (40, 48) is variable.
