Braking device for a vehicle, comprising a mechanism for driving at least one friction member in frictional engagement with a rotary member to be braked, the mechanism comprising a wedge (28) movable in a first axis in order to shift an actuating member (14) of the brake under the effect of a force coming from an actuator (34), characterized in that the actuator (34) comprises a centrifugal assembly (34) equipped with at least two flyweights (40; 72) arranged about a second axis and intended for rotating selectively about this second axis, the rotation of the flyweights (40; 72) about the second axis causing them to move away from the latter, and a connecting assembly (36, 30; 76, 90) between the flyweights (40; 72) and the wedge (28) for converting the movement away of the flyweights (40; 72) into a movement of the wedge (28) in the first axis.
