Technical Uneven Clutch

I simply get more and more amazed by the day of how wonderful you guys really are. :)

Thank you very much for all the effort and I will keep you posted with the results as soon as I gave them.

Cheers and respect.
 
Just thought about something that didn't cross my mind before.

I started noticing this after installing new brake pads on the rear wheels. I spoke to my father as he drove the car a little until it got registered and I came for it, and he said he always thought my clutch was a lot better than his and was gripping excellent.

Could some air have entered the installation in the process and cannot get out anymore? The pads were worn more than 95%.

That's the thing, I wasn't near the car when they changed them, so maybe some air did get in and they just put everything back really fast and pretended it didn't happen. I remember them saying I need to pulsate the brake a lot before driving it for the pads to arrange.

Anyway, tomorrow is the big day. I already called for a quote on the cylinders and pump and it raised to about 180£. If bleeding doesn't fix it, I'm afraid I have no choice.
 
They feel spongier than the other Stilo, kind of elastic really, and I have to press the pedal pretty down to get the brakes, a lot lower than the other Stilo. Kind of around 65% biting point, 100 being pedal fully up, and 0 being fully down.

Since changing them, I've driven the car more than 1500 miles.

So do you suggest just making a reservation at the dealers to replace the fluid and let them check or should I proceed tomorrow with the bleeding anyway?

I put my finder inside the fluid, it's pretty clean and very sticky kind of like liquid soap, the ones you find in the bathrooms of malls etc. Is it suppose to be like that?

This sounds more and more like a serious problem and I'm afraid I just can't escape without a substantial sum of money. Oh well, that's that.
 
With a very cheap self bleeding kit available from all car accessory shops then replacing the brake fluid is an easy one man job. Just put the new fluid in the top and bleed the old stuff out the bottom from each of the calipers. It will get rid of the old and contaminated fluid that collects in the calipers. Do the same for the clutch slave cylinder

I will try that and keep you guys posted. Thank you very much for your help.

I believe we've made a very good thread so far, a lot of people with similar problems can benefit. :)
 
Update: I have changed the fluid in the system. Tried do figure out how to do it myself, but without the device to push the fluid out it was extremely hard so I took it to the dealers. 1 hour and 50£ later, they gave it back to me.

I told them about the clutch problem and they said it should go away after the change, at least for a short period of time if the cylinders are shot.

Took the car to work, it feels kind of the same. Brakes are sharper though. They tested them as well, and they gave me a piece of paper on how they work, and they were good, no major difference between wheels.

So basically I'm starting to think its normal and I should live with it the way it is. They looked for leaks and couldn't find any. Maybe when the clutch cylinder is cold it feels a little different than when I press it lots of times. Anyway, I could always perfectly shift gears without any problems whatsoever.
 
Just remembered something. After waking up from a dream in which I was basically pissed that the car gave up on me and was pressing the clutch but nothing happened (this much it annoys me), it suddenly hit me.

Once upon a time (this is not an actual dream), I felt some clicking sound in the clutch. It felt at about 20-25% of the course (0 - fully up, 100 - fully pressed). I first thought, oh dear, the ball thingie is giving up on me, but then I was happy it went away.

Pretty soon after the symptoms appeared. What does this mean?

Basically they checked the whole hydraulic system, no leaks anywhere. Changed the fluid to Tutela Top 4, braking is smoother but the clutch still has the same annoying features.

I'm pretty convinced I need to change something, not really sure what, really. Already started saving money, so if you could please advise I would be very grateful.

Thank you very much to all of you.:)

Have a look at this long thread Vlad:

https://www.fiatforum.com/stilo/14491-clutch-pedal-click-clunk-squeak.html

If the plastic parts behind the pedal are worn or broken, it could be your clutch master cylinder push rod isn't getting enough travel.

The arrangement for your LHD car will be slightly different to the RHD pictures in the thread but it uses the same plastic parts.

Yeah but this should mean that the pedal should stay down all the time.

Symptoms are if I leave it over night or so the pedal is fine for the first 25-30 presses, then it starts lowering itself up to a certain point. Am I making any sense?

Anyway, I hope I get a chance to film everything and post before and after so you guys can see the changes.

The clutch is very smooth and the clicking sound has completely stopped. I does make sense to check it anyway.

Do you think it has nothing to do with the clutch pump, as I am being told?

LE: Thanks Deck, will check to see. I've noticed it being loose before.

Dave, read the whole thing before, was the last one to post on it. :) Will try to figure out if that is the case as well. Maybe the problem really is with the pedal and everything else is fine. I would be glad because it's cheap to fix, right?

On the same idea of the pedal not getting fully up and getting a full shot of fluid then make sure there's nothing simple like the above the pedals sound deadening panel getting in the way and preventing the pedal getting fully up

Mine was really getting in the way so I took it out and threw it away.

Can you see where the pedal was scraping against the panel every time. That caused me a lot of moving clutch bite problems when I first bought the car due to this interference

It may be totally different for lh drive. Try putting your foot underneath the clutch pedal and making sure it gets fully up

I've checked both the plastic ball thingie and the plastic covering to see if it touched the pedal in any way. They seem fine.

So like I promised, I made a short video of the problem so you can see exactly what annoys me about the clutch.

Would really appreciate more of your help. :)
