The brake system BS of the human-powered vehicle 2 includes a disc brake caliper 10 and a disc brake rotor 11. The operating device 4 is configured to supply hydraulic pressure to the disc brake caliper 10. The disc brake caliper 10 is configured to apply a braking force to the disc brake rotor 11 in response to the hydraulic pressure supplied from the operating device 4. The disc brake rotor 11 is rotatably coupled to the vehicle body 2A about a rotation axis RA. The disc brake rotor 11 is rotatable relative to the disc brake caliper 10 about the rotation axis RA.

[0068] When the human-powered vehicle 2 moves forward, the disc brake rotor 11 rotates relative to the vehicle body 2A in the driving rotation direction D11. When the human-powered vehicle 2 moves backward, the disc brake rotor 11 rotates relative to the vehicle body 2A in the opposite rotation direction D12. The opposite rotation direction D12 is the opposite direction of the driving rotation direction D11.

[0069] In the present application, the term "human-powered vehicle" includes a vehicle that travels with power, and the power includes at least the human power of the user riding the vehicle. Human-powered vehicles include various types of bicycles, such as mountain bikes, road bikes, city bikes, cargo bikes, hand bikes and recumbent bikes. In addition, human-powered vehicles include electric bicycles known as electric vehicles (E-bikes). Electric bicycles include electric-assisted bicycles that are configured to utilize electric motors to assist the propulsion of the vehicle. However, the total number of wheels of a human-powered vehicle is not limited to two. For example, human-powered vehicles include vehicles with one wheel or three or more wheels. In particular, human-powered vehicles do not include vehicles that use only a driving source as power. Examples of driving sources include internal combustion engines and electric motors. Generally, light road vehicles including vehicles that do not require a driver's license for public roads are considered human-powered vehicles.
