Dear friends, here I am back with the solution to my clutch problems. Indeed my problem was in the clutch master cylinder (it's really a brake master cylinder)
I released the three bolts that join it to the booster, here there is only a mechanical exchange and it does not share fluids.
I took the master cylinder to a place where they rectify brake discs and also do maintenance on these pumps, they changed all rubbers, they made a burnish in the tunnel, they cleaned and lubricated everything, they put it together, primed it and i put it in its place.
Only one of the cups was hard to find, the largest and the cost was about $100.
I would like to get that big cup in the United States or Canada, in the catalog it has the number 25, I attach a screenshot of the manual.
I thank everyone for the desire to cooperate and their valuable advice. In fact, I did an engine overhaul on this beautiful machine a couple of years ago.
I live in Chile, in the south of South America and here it is very difficult to get spare parts but I am in love with this "old faithful insect" and I think that I would only change it for a series 4 a few years newer and I would also like to buy it in North America, I appreciate any information some for sale.
