Hello, chaps

I have a fiat uno 1.7 60DS 1993, I'm having problems with my clutch system, the pedal travels ok and works the clutch, if I press the pedal vigoriously, however if I press the pedal lightly with no force at all, it has no pressure and sinks to the floor without working the clutch.

I have changed the slave cylinder for a new one about three months ago and all seemed fine at the time.

I have no leeks in the system and it has been fully blead several times, however I have noticed that the master cylinder is pushing pressure back to the fluid reservoir.

If it were the Clutch master cylinder at fault, where can I locate one from for a fair price? as I am having difficulty sourcing one here in the Midlands.

I would be very grateful for any advice here and suggestions

Many thanks

Ricardo

Welcome to the forum :wave:

Well, just to confirm your thoughts... I've experienced that sinking feeling with the brake master cylinder before (only under light pressure; hard pressure forces out the seal cups which then, err, seal ) So I expect that would apply to the clutch master cylinder as well.

Is this not an easy part to order from a FIAT dealer?

At a guess I'd say that you could replace just the seals in the cylinder, IF you can get it apart and the bore is not corroded or scuffed. The seals would have to be sized up by a 'brake and clutch' parts shop. Presumably they would rather sell you a complete cylinder, which is fair enough... Best of luck! (sorry I can't be any help with finding parts in the "midlands", since I'm about 14,000km from there )

Ok thanks for that Alex, you have confirmed my thoughts to the sinking feeling with the foot pedal.

Guess I shall have to remove the driver seat and steering wheel, and lay on my back for a while getting at the darn thing, when I have located a replacement???????????

Hi there, i have a couple of 92/3 unos for breaking, petrols, but clutch master cylinders might be the same?

Cheers Trevor.

Ok thanks for that Trevor, however I think a new replacement would be the better option, considering the time and effort to change the unit, and I feel that a new unit would be less likely to fail than a second hand one.

Cheers

Excellent
I'm always really surprised when something is actually in stock!

Now, what took five hours with the fitting/what was the worst part?

-Alex

After removing driver seat and steering wheel, on your back with your head in the foot well, the retaining clip on the pin was the most difficult to remove, as it sits close to a bracket, about half an inch I would say, not a lot of room to get at it directley

Replacement of the pin to the new cylinder lever was very tight, and would not go fully seated for the reaining clip to fit back on, so some gentle, but firm tapping with a small hammer took a while to get it seated.

All done on my jack jones without the aid of an assistant

I see - thanks for the summary
Now I just have to look up what 'jack jones' means

EDIT: This was useful http://www.cockneyrhymingslang.co.uk/slang/jack_jones
but most of the other results seemed to reference a musician

-Alex

Sorry for the confusion my old sport with Jack Jones

Jack Jones is a singer, his father was also a famous singer and appeared in several films.

It's BRILLIANT on petrol, I haven't filled it up since April! I remember reading about someone with a V8 petrol Range Rover who found it was the most economical vehicle they'd ever owned - because they avoided any unnecessary trip in it...

My friend James was the last to fill up the 164 - he used it for a ~3hr return trip with passengers, and before that it towed the project Uno home on a trailer.

It can return anything from 20mpg around town to 40mpg on a decent trip. And, comfortably over 30mpg when towing an Uno on a trailer. If you have a task that needs the 164, it's an economical car for the task

I drive my 164 about once a month and the experience is worth every minute. When considering the running costs, you also have to bear in mind that the car cost $1000 to purchase (about 340 pounds). :slayer:

I don't really have an 'everyday' car because I don't need to go anywhere every day. In fact I was thinking recently that cars are something of a self-fufilling prophecy - most trips I make have something to do with the car itself. At the moment, the project Uno is the first choice of transport, but after that disappears next week, I'll use my Punto until that gets its driveplate replaced soon, and then I'll drive the Uno Turbo unless its raining, in which case I'll take the 164. Or the scooter.

Even though it's something of a last resort, as you might have guessed by now, I love my 164. It's a competent machine that feels great to drive and is made out of good-quality stuff, and I think the styling is fantastic, perfect proportions. It's really quite different to any other Alfa Romeo before or since. Also I've owned the FIAT Croma and the Lancia Thema, and I'd say the 164 is the overall best of the bunch, though the Lancia/Saab have their own character - the 164 has aged better.

In the summer I expect to invest some time and money in restoring my 164. The engine needs to come out to fix a few minor leaks, the clutch needs replacing (doesn't slip but it's super-heavy), and the front end could do with a respray (chips and scratches - no rust!). I ought to figure out why the passenger's seat motors require a tap from a hammer to get them moving. Also I have a replacement compressor for the climate-control. After all, it has done over 240,000km (150,000 miles).

Rather than undertake this work, earlier this year I decided to buy a 166 instead. That was a 2002 3L V6 auto and had done just under 100,000km. It turned out to be a lemon and I sold it a month later at a $2000 loss, for $7000. The next owner easily spent another $2000 on it. I don't think the 166 is a patch on the 11-years-older 164. My dB meter confirmed that the 164 was quieter (yet the 12V engine sounds better than the 24V) and the 164 is considerably more economical, with quicker acceleration (lower-down torque than the 24V). It's made out of better materials too - the 166's beauty is only skin-deep and the body bends like a banana. And at a count of 15, the 164 has a lot more interior lights

I notice you have a GTV... though I must confess the photo was so small, when I first saw it I thought it was an '86-'91 BMW 3-series

-Alex

Alex!

Thats not a GTV it's an Alfasud Ti 1978 33,000 miles on the clock, its been laid up since 1991 and only started once in a while during the year

How stupid of me - sorry!

So you don't drive this 'Sud very often, then. I guess that avoids the rust problem?
