Abstract: An electromotive brake system may include a caliper housing, a first and second friction pads, a brake disk disposed in between, a pressurizing member connected to the second friction pad, a push rod with a push rod groove, an operating disk inserted in the push rod groove, first and second springs, a rotating ramp adapted to convert the rotational movement of a motor into a linear movement of a non-rotating ramp by a ball disposed between the rotating ramp and the non-rotating ramp. The electromotive brake system may further include first and second catching portions, a plurality of teeth and corresponding engaging protrusion of the teeth. The plurality of teeth and the protrusion may have slanted or curved surfaces.
