Problems with the Peugeot 406 clutch of 2002

Hello everyone. I have the problem I have with a Peugeot 406
I have changed the clutch kit of a Peugeot 406 and the Bimasa seems to be fine. After changing it and trying it and seeing that it was going well, on the second day the liquid had lowered a lot and the clutch was still going. After filling it, the clutch's hype has changed and we have seen that the liquid goes back after having purged and filling it.
The truth is that I am a little lost and I turn to you in case you can illuminate me a little on the subject.
Greetings to all and thanks in advance

You have to check where the liquid is lost if it is not for the pump you follow the pipe to the auxiliary cylinder if it does not have this cylinder then the thrust bearing is hydraulic, if this is the case it would be the case it would be liquid from the box itself.
