Abstract
The invention relates to a braking apparatus having an electric service motor, which serves to actuate a brake via an actuating device. To enable adjusting an air clearance, the invention sets forth a helical gear and a load moment block, which blocks the helical gear against adjusting itself independently and allows adjustment by means of a readjusting motor. To adjust or establish the air clearance, the brake is actuated with the readjusting motor, until a brake lining contacts a brake body, such as a brake disk, and then moves backward by a defined distance. If the service motor and/or the actuating device fails, the braking apparatus can be released with the readjusting motor. In order to achieve a parking brake function, the invention sets forth a second load moment block for the actuating device.
