Abstract
An automatic adjusting device for a mechanically acutated sliding-caliper disc brake has a mechanically actuated device for moving the sliding caliper relative to the brake disc comprising an oblique-track spreading device which has an actuating shaft, an adjusting nut coupled to the actuating shaft through a rotational ratchet mechanism which is operative when the actuating shaft is turned in the brake actuating direction, the rotational ratchet mechanism being formed as a positive-engagement saw-tooth ratchet having structural arrangements made so that when the actuating shaft exceeds a certain torque one section of the coupling yields axially against the force of a precompressed spring without transferring rotational movement to the adjusting nut.
