Peugeot 605 clutch system

Hello: I have a 605 SVI 3.0 of the year '96 and the clutch broke. It turns out that the pedal goes to the bottom and does not act. I took him to the mechanic and did not give on the key: he disarmed all the pedalie and nothing. He says that the problem is in the "Bombín" but the truth is that I do not know if to believe ... spare parts do not abound and specialized labor either. If someone can advise with something I will be much more than grateful. Greetings, Jose.

José This model is mounted with a hydraulic clutch system, if the bombin fails or the pump the pedal is stuck down and does not return, but first Czech that has liquid, if you do not have to see where it boot it, usually I change the two things at the same time since if you make work a new component with an old thing is most likely that it ends up breaking the old man.

Thank you very much Kikemec !! It is very useful for the information you provide. I hope to find the right mechanic and solve the inconvenience. Greetings, Jose.
