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.

Abstract: A bicycle hydraulic operating system includes first and second actuating devices and a hydraulic operated device. The first actuating device includes a first operating member, a first master cylinder and a first master piston. The first master piston moves in the first master cylinder in response to operation of the first operating member. The second actuating device includes a second operating member, a second master cylinder and a second master piston. The second master piston moves in the second master cylinder in response to operation of the second operating member. The hydraulic operated device includes a slave cylinder and a slave piston that is movably arranged in the slave cylinder. The slave cylinder has a slave fluid port that is connected to first and second fluid ports of the first and second master cylinders. Operation of either of the first and second operating members moves the slave piston.
