The invention concerns a brake disc cylinder comprising a parking brake mechanism consisting of an input shaft designed to be driven in rotation when the parking brake is actuated, a ball ramp (12) comprising an input plate (11), integral in rotation with the input shaft, and a mobile plate (13), balls (14) being housed in the grooves (15) opposite the two plates, a play take-up screw(24)-nut (19) assembly, integral in rotation with the mobile plate of the ball ramp and with the piston forming an adjustable spacer between the mobile plate and the piston, by unscrewing the screw in the nut. The screw (24)-nut (19) assembly comprises a screwing pitch oriented such that compression of the screw-nut assembly generates a rotational torque countering the drive of the mobile plate by the input plate when the latter rotates. The invention also concerns a disc brake provided with such a cylinder and a set of at least two disc brakes for a running gear comprising at least a first wheel provided with a first brake mounted on the right hand side of the wheel and a second wheel provided with a second brake mounted on the left hand side of the wheel. |
