A self-energizing disc brake includes a brake-internal hydraulic arrangement with a supply circuit and an expansion vessel; a brake application device having a cylinder for applying a brake pad toward a brake disc; a force transmission unit supporting the brake pad at a wedge angle on the brake application device; a tangential-force absorbing cylinder for switching over the wedge angle, which is operatively connected to the force transmission unit; an electric-motor actuator for acting on the brake application device via the hydraulic arrangement; and a control unit. The force transmission unit has a deflection lever and a shoulder element attached thereto. Rolling surfaces thereof are in contact with respective corresponding rolling surfaces of a brake application element of the cylinder and a brake pad support device. The deflection lever has a pressure section with a rolling surface in operative connection with the tangential-force absorbing cylinder.
