摘要

A method for detecting a leakage in a hydrostatic actuating device (102) for a friction clutch a direction (100), the actuating device (102) comprising at least one master cylinder (114) with a master piston (116), at least one slave cylinder (118) with a slave piston and at least one hydraulic section (120) with a pressure sensor and / or position sensor between the at least one master cylinder (114) and the at least one slave cylinder (118), the friction clutch a direction (100) comprising at least one with the aid of the actuating device (102) is limited axially displaceable pressure plate (106), characterized in that, during an operation in the case of actuation of the friction clutch a direction (100) in a predetermined direction of movement of the friction clutch a direction (100) of the pressure in the hydraulic path (120) with the pressure sensor is monitored and with a defined pressure - limiting characteristic curve (206) is compared.
