Abstract: An application device for a compressed-air-operated disc brake with a turn lever, an eccentric and two parallel male-threaded adjusting spindles, each of which acts via a pressure member on a brake pad and which are coupled together rotationally fixed via a synchronising device, in which an axially movable adjusting device is arranged to be integral in rotation in at least one adjusting spindle and, at every actuation of the turn lever, exerts an adjusting torque on the appropriate adjusting spindle which the synchronising device transmits to an adjuster or an actuator in the other adjusting spindle. The synchronising device is a shaft running in the region of the axis of the eccentric having a bevel gear on each face which meshes with a corresponding bevel gear of the adjusting device or the actuator.
