I thought I'd start a new thread specifically for the Uno Turbo conversion (for those who don't have large wheels ), rather than infest the Punto GT thread any more.

Basically we've established that what is needed is:

• Uno Turbo brake discs
• Uno Turbo calipers
• Uno Turbo brake pads
• 3mm spacer machined down to fit behind the disc

What else is needed?

Specifically, do the current hoses fit onto the new caliper, or will I need to purchase Uno Turbo hoses, or can I get new Goodridge hoses for a Cinq?

Will keep you updated when I actually get some of the parts....
Anyone got some calipers for me?

Thanks

hoses will fit but obviously a sensible time to change them

As suggested , cinq sized hoses will be fine, and you seem to have the full list of parts, remembering you need the caliper carrier, not just the caliper itself.

Since I have uno turbo alloys I should get the brakes

Where can I get the spacer from?

Also, how much better are the uno turbo brakes?

you already have the spacer on your wheels but as said it needs machined down to fit inside the disc rather than out side

They are vented discs so disappate(sp) heat better when used hard. Ultimate performance depends upon the grade of pad material fitted.

How often should they be changed then?

I assume that the thread on all Fiat calipers and hoses are the same so in theory any caliper would screw onto the Cinq hose.

not really a service item but they do wear and if you plan to fit goodridge at any time then with a caliper change it makes sense

Standard rubber hoses become weak over time and some of your pedal pressure goes into making the hoses expand. Even when new there will be a small amount of, I can see trouble brewing here, but I'll still use the term, hose expansion.

Fitting teflon lined steel braided hoses reduces this flex, and maintains that state for longer.

[*]3mm spacer machined down to fit behind the disc[/LIST]What else is needed?

Bit confused, elsewhere ( https://www.fiatforum.com/cinq-sei-technical/22550-recommended-modifications-2.html ) I've seen "10mm spacers machined down to 9mm fitted between hub & disc, or the use of a 1mm washer on the calipers" mentioned.

Is the 3mm spacer thing meant to refer to having 3x3mm spacers machined down rather than messing about with 1x10mm one & washers?

Or am I missing something completely?

Hi guys, never heard back to my above question on this thread - for interest I've uploaded a pic of the Seicento (left pic) & UT (right pic) front brake assembly from the FIAT ePER.

My collection of bits:

Black Diamond Drilled & Grooved UT Discs = £130
Black Diamond Predator UT Pads = £45
UT Calipers = £20
Remanufacture & bright red Polymer coat by www.BiggRed.co.uk = £160
Cinquecento Wheel spacers = £14.64

The spacer referred to is item 8 on the Seicento assembly diagram.

I've bought a couple new from my local Research so I could do the grinding work before I took the car apart, but having looked the @ the ePER the part # is different on the Sei to the Cinq'. All I can tell is that in the ePER description the Sei part looks like it weighs far more - anyone got any idea what the difference between the Cinq' & Sei spacer is?

I'm pretty sure I got the Cinqy one but I've already ground them down to fit inside the disc bell? :-( Suppose once I give it a go I'll know the answer either way!!!

Guessing I need to leave item 3 (Seicento) on & that this is the bit that the caliper bolts to?

Sorry if any of these questions seem silly & would be obvious once I'm started, but I'll be doing the work @ a friends garage for free & I don't want to get halfway through & find out I've missed something vital.

I'll create a guide, taking photos as I go along when I do the work.

remember there are 2 types of spacer on the sei.
the 3mm spacer like the cinq and the 10mm hubcentric used on the abarths so that maybe the difference.
as oyu have said once your fitting its all pretty obvious and its far less daunting than you think

I am pretty sure item 3 is just the tin backplate, Its your choice whether to leave it or remove it. Mine went in the skip.

Its the thinner Cinq sporting spacer you need which sounds like the one you've got.

Thanks guys, just trying to avoid the scenario that GhostWKD hit in the following thread https://www.fiatforum.com/cinq-sei-technical/65611-ut-brakes.html of being left without brakes unless I re-fit originals, especially as my Cento pads are getting really low.

Rallycinq, I had wondered if that is what it was, I'll be junking that then if it doesn't fit or seem to be doing anything useful when I match up all the bits.

This is the post that has left me confused though...

Fact 5. If fitting the Punto GT disc there is no way any caliper can fit under a 13 inch wheel.

I have Uno Turbo vented discs and matching calipers on the front of my Cinq, yes. I use Mintex 1144 material. I took the original Sporting front wheel spacers and had them machined down in diameter to fit inside the disc bell. I didn't have the spacer thinned from 10mm to 9mm, I use 1mm washers on the calipers.

Like I said, I know it'll probably become obvious when I try fitting, but by that time it'll be too late to complete the work the same day & where I do the work it'll be in a mate's garage doing me a favour after work or & the weekend.

I wrote that a while ago!!

It will become apparent when you get it all in bits. Make sure you have a box of assorted washers before starting.

The UT discs have a different offset to the PGT ones so that is why the spacer is needed inside. I used the Cinq Sporting ones cos thats what I had. The diameter was turned down so that the fit inside the bell of the UT discs.

Get them mounted up on the hub then offer up the caliper holder.

The disc needs to run centrally within the holder. This is where the washers can be needed. Once that is mounted up, add the caliper and Robert is your mothers brother.

I found that i needed 6mm spacers to go inside the discs not 3mm

Well, thanks for all the advice guys - job done & in the end I got away with using 3mm spacers ONLY!!!
At least this way the wheel bolts are still sitting as far into the hub as possible, I did it by grinding about .5mm off the face of the UT caliper holder on the side that was fouling the disc, then about another .5mm from the caliper holder where it mounts onto its bracket (still plenty thick).

Oh, & I found that my Seicento Mpi (which was on original discs & pads with stock wheels) had no spacer on so I was really glad I'd bought a fresh pair from Research to grind down in advance

Now just gotta' drive like a granny for a couple of hundred miles 'til everything beds in!!!

I agree with you Ghost...im sure the UT setup i got off Arc had a 6mm spacer to go between disk and hub,deffo not 3mm

great stuff Paul I will have to check them out sometime as your not too far away

you doing a Ut rear?
