2. A braking system for a vehicle, comprising:
at least one hydraulic braking circuit;
at least one electromechanical or electromagnetic wheel brake cylinder, which is respectively associated with a wheel of the vehicle and is respectively linked to a respective sub-volume of the at least one hydraulic braking circuit, each of the at least one electromechanical or electromagnetic wheel brake cylinder including:
a pressure chamber that is situated in the electromechanical or electromagnetic wheel brake cylinder and is delimited by a displaceable first brake piston of the electromechanical or electromagnetic wheel brake cylinder, and the pressure chamber being linkable to the respective sub-volume of the at least one hydraulic braking circuit of the braking system in such a way that the first brake piston is displaceable by way of a pressure that is increased at least in the respective sub-volume,
an electromechanical or electromagnetic actuator, and
a second brake piston of the electromechanical or electromagnetic wheel brake cylinder which is displaceable by operation of the electromechanical or electromagnetic actuator; and
a motorized brake pressure buildup apparatus configured in such a way that by operation of the motorized brake pressure buildup apparatus, at least one pressure respectively present in the at least one sub-volume of the at least one hydraulic braking circuit is increasable;
wherein the braking system has, for each wheel of the vehicle, a respective electromechanical and/or electromagnetic individual-wheel brake or the at least one electromechanical and/or electromagnetic wheel brake cylinder.
