Abstract

A disc brake is provided having an electromechanical actuator, which is designed as an electric motor, for actuating a brake application device for applying the brake, which disc brake has a self-energizing device, characterized in that the electric motor acts directly or via a gearing on a rotary lever which acts on at least one brake piston which moves a brake pad parallel to the brake disc rotational axis, which brake pad is moveable both in the direction parallel to the brake disc rotational axis and also parallel to the brake disc friction face.
