1. A friction brake system for a vehicle, comprising
a braking member connectable to first and second brake pads and configured for pressing the first and second brake pads against a friction surface, and
a transmission unit configured for converting a rotary motion generated by an electric motor into a braking motion of the braking member,
wherein the transmission unit comprises a ball-in-ramp assembly having:
a first plate with at least one groove,
a second plate with at least one groove facing the groove of the first plate, and
at least one ball arranged between the first plate and the second plate, wherein the ball is retained by the groove of the first plate and the groove of the second plate;
wherein the ball-in-ramp assembly is configured to convert a rotary motion of the first plate into a translational motion of the second plate with respect to the first plate,
wherein the first plate is configured to be rotated by the electric motor and at least one of the first plate and the second plate is mechanically coupled with the braking member such that a rotation of the first plate causes the braking motion of the braking member, and
wherein the first plate is rotatably supported by a brake bolt bracket coupled to at least one braking bolt, and the second plate is operably connected to a caliper housing bolt connected with a caliper housing such that the caliper housing and the braking bolt are configured to press the first and second brake pads against opposing surfaces of a brake disc when the braking member executes the braking motion, and
wherein the second plate is connected to the caliper housing bolt through a hole formed in the first plate.
