golf clutch mk 4

Hello my name is Mauricio, I have a problem with the clutch, the pedal has been down and I feel that it has no pressure, that is to say that it goes to the bottom and does not return, in addition to being there the marches do not enter. They told me that it can be the hydraulic system pump, the truth is that I do not know anything and I would like any expert to clarify the subject, thank you very much

Friend send me clutch images (pedal, motor compartment, gearbox)

I do not have the car at this time, I had to leave it since I could not move it, it is the 1.6 comfort version, it is of Brazilian origin

Hi Mauricio, of the systems that are, if it is by cable and stays "low", put that you have problems in the clutch or diaphragm mace (with changing the maza-Embrague assembly) is solved, it may also be that the cable is "flash" under the pedal. If the system is hydraulic, there will be liquid stain due to the breakage of the master cylinder or in the slave cylinder (inside the box) or that the system has air (as well as a brake circuit) and you have to purge it. In the case of this golf, it may go by cable, greetings !!
