A radial piston machine includes a multi-disc brake, a brake disc assembly of which interacts with a first annular section on a drive shaft and a second annular section on a housing. The brake disc assembly is disposed within a brake chamber. The first annular section and the second annular section each delimit the brake chamber in sections. A disc section, a spring, a brake piston, and the brake disc assembly are disposed next to one another in a specified sequence along an axis of rotation in such a way that a force of the spring is transmitted to the brake disc assembly.

An electromechanical brake for a motor vehicle. The electromechanical brake includes an electric motor which drives a spindle drive unit via a transmission unit, via which spindle drive unit a brake actuator is axially movable for braking. A drive housing which accommodates at least the transmission unit and the spindle drive unit is provided. The drive housing is provided as a separate part to a brake clamp encompassing a brake disc and is connected to the brake clamp. The drive housing is formed by two interconnected housing parts, at least the transmission unit being arranged in a first housing part and at least the spindle drive unit being arranged in a second housing part.
