An operating device comprises a base member and an operating member. The base member is configured to be mounted to one of a dropdown portion and a bar end portion of a handlebar. The base member includes a cylinder bore and a reservoir bore. The cylinder bore has a cylinder center axis. The reservoir bore has a reservoir center axis. The operating member is pivotally coupled to the base member about a pivot axis. The cylinder center axis is offset from the reservoir center axis in a pivot axis direction parallel to the pivot axis and in a perpendicular direction perpendicular to both the pivot axis and the cylinder center axis.

A hydraulic block, the upper side of which is provided with a brake-fluid reservoir which is fixed in place on the front surface and on the rear surface of the block by fastening apparatus/device (arrangement). The front fastening apparatus/device (arrangement) is formed by a tab that projects from the underside of the reservoir, this tab being screwed to the front surface of the block. The rear fastening apparatus/device (arrangement) is made up of a tab, which projects from the rear side of the reservoir and is formed by a hook that is supported by a carrier that is fastened to the rear side of the hydraulic block and forms a support for the tab, as well as a clamp, which connects the tab to the hook.

A brake-actuating device for a vehicle brake system comprises a fluid reservoir and a master cylinder arrangement. The fluid reservoir has an outlet connection, and the master cylinder arrangement has an inlet connection. The outlet connection of the fluid reservoir and the inlet connection of the master cylinder arrangement, in the connected-together state, define at least one axially overlapping connection region through which a fluid channel for the feed of fluid from the fluid reservoir into the master cylinder arrangement extends. Furthermore, the brake-actuating device comprises a sealing element, which is arranged in the connection region and seals off the latter to the outside, and a filter element for filtering the fluid to be fed to the master cylinder arrangement. The sealing element holds the filter element in a predetermined position in the fluid channel.
