Abstract

A brake control device is configured such that a hydraulic braking device is provided for one of a front wheel and a rear wheel, and an electric braking device is provided for the other one of them. The electric braking device is provided with a mechanism configured to prohibit retreat of a piston for pressing friction members against a rotor that rotates with the wheel. The brake control device is configured to maintain, by an operation of the mechanism, a braking force that does not depend on a force of an electric motor as a drive force and to control a braking force generated by the hydraulic braking device based on a difference between the braking force thus maintained and a braking force requested for the electric braking device.
