Abstract
A vehicle parking brake system for a vehicle including: a non-rotary body; a rotary drum; brake shoes; an anchor member disposed between anchor-member-side end portions of the respective brake shoes; a transmitting member interconnecting transmitting-member-side end portions of the respective brake shoes; and a parking-brake operating apparatus configured to predict a torque application direction in which a torque is to be applied to the wheel during stop of the vehicle, and to press the brake shoes against an inner circumferential surface of the rotary drum, by moving a primary one of the brake shoes that serves as a primary shoe upon application of the torque to the wheel, in a direction away from the anchor member, without moving a secondary one of the brake shoes that serves as a secondary shoe upon application of the torque to the wheel.
