Seat Cordoba SDI Manual

Hello friends, I am having problems with the change of my Seat Cordoba 1.9 SDI of the 2000.
The Pedal del Embage went down suddenly and no longer climbed, I have changed the two hydraulic hypes and still does not work, I have purged them and nothing at all, I fear that the breakdown is inside the box.
This is why I need a partner of the forum to send me the workshop manual of this model or a link to lower it, specifically is the exchange box and more concrete in the thrust zone of the vila that is near the wheel pass, since before opening I would like to have detailed information on this.
The lid that closes the change in this area can be removed if problems? How, pulling out? , it gives me that from that lid you can access the clutch thrust mechanism.
I already have the Golf SDI handle, but I need broader detail of the thrust zone, where is the round cover with the VW logo
thanks to colleagues beforehand.
