Technical clutch pressure

[gr33ngiant]

Hi Guys and Gals,

Not too sure if this is the right forum to post help questions in, if not just let me know and I wont make the same boo-boo in the future.

Anyways my clutch went pressureless on the road yesterday, Im driving a Fiat 99 model, 1100. When switched off the gearstick happily shifted through gears. Of course since the clutch was basically falling to the floor when i pressed it due to lack of pressure the car would stall if I had left her in gear upon starting it.

Now I'm a complete n00b when it comes to engines so I phoned up my best buddies dad who told me my lil uno probably doesnt have a hydrolic clutch but uses a wire instead, so my theory of an air pressure bubble forming due to lack of fluid (which there was, but I guess thats break fluid I topped up then since it uses a wire).

Im looking for some clarification here, is the clutch hydrolic or does it use a wire? And depending on the answer and the description of the problem (pressureless clutch) what can I do?

Any advice would be greatly appreciated.

If it didn't make any nasty noises, then it's the hydraulics, probably slave cylinder.

If there was a hell of a nasty noise first, then your thrust bearing has siezed and destroyed the clutch.

If it was a cable and the cable snapped, does the pedal fall to the floor and stay there or stap up and just sink when you press it?

Hi gr33ngiant and welcome to FF

Where are you from with the late Uno?

I’m not really sure on the late Uno TBH, but earlier Unos with a hydraulic clutch had the clutch fluid reservoir mounted on a turret – see below.
