BRAKE DEVICE FOR A HYDRAULIC MOTOR VEHICLE BRAKE SYSTEM

The invention relates to a brake device (1) for a hydraulic motor vehicle brake system without a vacuum booster, comprising a housing (2) with at least one pressure chamber (3) arranged therein, comprising a cylinder piston (4) which can be axially moved in an actuation direction (B) by means of an actuation rod unit (6) coupled to the cylinder piston (4) in order to generate brake pressure, wherein a rigid stop (14) is provided for the cylinder piston (4) which defines the unactuated starting position of the cylinder piston (4). In order to provide an improved brake device (1) of the above-mentioned type, which permits simple and reliable detection of the zero point, and simultaneously has reduced noise emission in the return, according to the invention, a damping element (7) is providedwhich permits a mechanical decoupling of the actuation rod unit (6) from the cylinder piston (4) in a release direction (L) opposite the actuation direction (B) by means of a reversible deformation. 本发明涉及一种用于不具有真空助力器的液压式机动车制动
