Abstract

A brake control device includes an electronic controller that is configured to control a braking unit that is configured to brake at least one of a plurality of rotating bodies of a human-powered vehicle. The electronic controller is configured to control the braking unit upon determining an ABS control is performed to decrease a braking force of a first rotating body included in the plurality of rotating bodies so that a braking force of a second rotating body, which is different from the first rotating body and included in the plurality of rotating bodies, is increased by a force that is different from hydraulic pressure.

First claim
