Hydraulic bicycle brake actuation mechanism - has ring shaped extension to form hydraulic oil pipe connection piece.

摘要

The brake has a connection for an oil pipe consisting of a housing side bore (31) with a ring shaped extension at one end (32). The ring shaped extension runs from an opening (30) for the conduction of a fluid, preferably oil, from an oil pipe (17) to a hand brake cylinder (11). The circumferential wall of the bore (31) is wave shaped. ADVANTAGE - Ensures a reliable seal between the cylinder and the oil pipe without the need for a screw fastener.
