Clutch - manual gearbox

[Kip W211]

Hi

The problem appeared a few days ago, clutch does not return completely after pressing, pedal is wet - some sticky fluid. There is a kind of a small ,,piston,, from which probably leaking the liquid. You think this is the reason? I change it myrself? How to go about? oi it is best to visit the workshop?
