The present invention relates to an electromechanical braking device (1) for a motor vehicle, comprising an electromotive adjusting device (5) and a braking element (32) which is connected thereto and can be adjusted by the adjusting device (5) and brought into braking engagement with a counter-braking element (2), wherein: the adjusting device (5) has at least one adjusting drive (6, 7); the adjusting drive (6) has a ball-ramp arrangement (6) comprising two cam disks (61, 62); the cam disks (61, 62) can be driven by an electric adjusting mechanism (41, 42) such that they rotate relative one another about an axis (A), and have raceways (64) that are axially opposite each other at an angle relative to the axis (A), between which raceways one ball (63) is arranged such that it can roll; the raceways (64) have an at least partially rounded-off cross-sectional profile with a raceway radius (rg), and the ball (63) has a ball diameter (Db). In order to implement an improved function having an optimized recovery characteristic, according to the invention, a ratio (C) between the raceway radius (rg) and the ball diameter (Db) is greater than 0.5.
