  • Publication number: 20200189540
    Abstract: 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.
