If your pressure point is like a melted piece of butter and/or you can pull your lever behind your bar, you should bleed your brakes.
To avoid a mess and getting dirty wear gloves and an old shirt and keep a cleaning cloth on hand. Wear safety glasses to protect your eyes from dust and/or liquids.

Und warum tritt an bremszylinder an der Entlüftung schraube bremsflüssigkeit aus?
wir haben alles so gemacht, wie beschrieben, aber es tritt am entlüftungsnippel Öl aus und Luft????
Bei welchem Schritt tritt denn die Bremsflüssigkeit am Entlüftungsnippel aus?
Grundsätzlich ist es normal, dass sich während dem Entlüftungsprozess ein wenig Bremsflüssigkeit am Entlüftungsnippel sammeln kann.
Wichtig ist, dass die Entlüftungsschraube während dem Entlüften nur minimal geöffnet wird, sodass die Flüssigkeit hindurch in das System gedrückt werden kann.
