Abstract
A motor-driven disk brake is capable of functioning as a parking brake satisfactorily without degrading the brake operating feeling and impairing the function of operating as a motor-driven brake. A stator and rotor of an electric motor are provided in a caliper body floatably supported on a carrier. The rotation of the rotor is transmitted to a piston after being converted into rectilinear motion through a ball-and-ramp mechanism and an adjusting nut. The piston, together with a claw member, presses brake pads against a disk rotor. A rotation assisting device is provided between the rear end of the rotor and a motor casing. A rotary disk constituting the rotation assisting device is rotated through a wire extending from an external operating member.
