  • Publication number: 20130228407
    Abstract: A master device for a closed hydraulic system of handlebar-steered vehicles includes a basic body and a pressure chamber in which, in the event of actuation of the master device in order to actuate a slave device, hydraulic fluid is placed under pressure. The master device includes a hydraulic line connecting element having a connecting piece for connecting a hydraulic line and a thread section for screwing into the basic body. An air bleed opening bleeds the hydraulic system. The hydraulic line connecting element and the basic body form a valve that closes the connection between the pressure chamber and the air bleed opening when the hydraulic line connecting element is fully screwed in to the basic body.
