Electromechanical brake having a gas-containing piston chamber

A brake system for a motor vehicle, comprising

• an electromechanical brake for actuating at least one brake shoe and comprising an electrical control device;
• wherein the electromechanical brake comprises:
• an actuating piston which is set up to be moved translationally in a direction of a piston axis in order to actuate the at least one brake shoe,
• a brake carrier having a gas-containing piston chamber in which the actuating piston is received such that the actuating piston can be moved translationally in the direction of the piston axis,
• an electric motor for driving the actuating piston;
• and
• a venting device extending from the piston chamber for venting the piston chamber with respect to an exterior of the piston chamber, the venting device comprising a venting line that is flow connected to an interior of an actuator housing that serves as an enclosure for the electric motor;
• wherein the electrical control device is for controlling the electric motor of the electromechanical brake, wherein the control device and the electric motor are set up to set a braking force exerted by the at least one brake shoe according to one or more specified values.

• an electric motor for driving the actuating piston;
• and
• a venting device extending from a side of the piston chamber opposite of the at least one brake shoe for venting the piston chamber with respect to an exterior of the piston chamber,
• wherein the venting device comprises a venting opening which is provided on the brake carrier and is flow-connected on the one hand to the exterior and on another hand to the piston chamber, and further comprising an actuator hosing which serves as an enclosure for the electric motor and is arranged on the brake carrier with formation of an interior,
• wherein the venting opening is arranged on a portion of the brake carrier which is located within the interior.
