    Abstract: Disclosed is a brake actuating apparatus which can perform braking without converting a rotational motion into a linear motion. The brake actuating apparatus includes a caliper body with a cylinder. An electric motor is fixed to the caliper body. A pressing piston is installed in the cylinder. A housing or plug is installed in and block the cylinder, and a rotational shaft is installed at the center of the housing to be rotated by the motor. A head is attached to the rotational shaft and defines a fluid-receiving space in cooperation with the housing. The rotation of head varies the volume of space, thereby moving the pressing piston.
