Abstract
A brake actuator comprises an electric motor, a conversion device for converting the rotational movement of the electric motor into a linear movement and a hydraulic transmission for transmitting the linear movement of the conversion device to an adjusting piston of a brake. The hydraulic transmission comprises at least two hydraulic pistons which independently of one another can be axially displaced in a hydraulic chamber, whose first hydraulic piston by way of a first driving element of the conversion device can be operated directly by the electric motor and whose second hydraulic piston can be operated by way of second driving element of the conversion device which can be taken along by a controllable clutch element by the first driving element.
