What I found out:
That there are two main types of cylinders, single seal piston and dual seal piston.
That your Alfetta can have the wrong cylinder configuration (the bleed nipple conflicts with the body of the gearbox when orientated upwards)
That the flexible rubber hose runing to the cylinder brakes down in time.
That the rubber particles from the afore mentioned hose get into the cylinder.
That the particles in time will bock the bleed port.
That you won't figure that out until it's too late and you have to pull the cylinder out clean every thing and put it back in.
And that it is quicker the second time through.

An Italian Haiku perhaps not, but definately Alfa Romeo Confucianism...very insightful Two Dogs.

I read on a parts book where the Alfasud, 33's Alfettas, Guilliettas all share the same slave cylinder repair kits [rubber seals and boots], but from what you say the castings for the slave cylinder body's may be different, on the Suds and 33's they have a solid line from the master cylinder to the slave cylinder, which makes them difficult to remove or replace, but the line won't stuff up over time and clogg everything up with rubber particles, Colin.
