Abstract: A brake caliper for a bicycle includes a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle. A brake pad is installed within the housing and is configured to move between a braking position and a non-braking position. The braking position is a location within the housing where the brake pad contacts the disc when the housing is installed on the bicycle. The non-braking position is a location within the housing where the brake pad is further from the disc than in the braking position. The caliper also includes a biasing member configured to bias the brake pad in a downstream direction within the housing with the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward.

Abstract: A hydraulic operating device comprises a base member, an operating member, a piston, and a mounting member. The base member includes a cylinder bore, a first hose-attachment hole, and a second hose-attachment hole. The first hose-attachment hole is configured to be in fluid communication with the cylinder bore. The second hose-attachment hole is configured to be in fluid communication with the cylinder bore. The operating member is pivotally coupled to the base member about a pivot axis. The mounting member is configured to couple the base member to a handlebar. The mounting member includes a mount opening through which the handlebar is to extend. The first hose-attachment hole, the second hose-attachment hole, and the mount opening are provided on a reference plane perpendicular to the pivot axis.

Abstract: An operating device for a human-powered vehicle comprises a base, a piston, an operating member, an intermediate member, and a mounting structure. The base includes a hole. The piston is movably provided in the hole. The operating member is pivotally coupled to the base about a first pivot axis. The intermediate member is pivotally coupled to the base about a second pivot axis to transmit a pivotal movement of the operating member to the piston. The mounting structure is configured to couple the base and a handlebar of the human-powered vehicle. The mounting structure defines a mounting axis extending along the handlebar in a mounting state where the mounting structure couples the base and the handlebar. The first pivot axis is closer to the mounting axis than the second pivot axis in a perpendicular direction perpendicular to the mounting axis as viewed along the first pivot axis.
