"That'll only take an hour or two"

Famous last words.

Right, on the Sporting Seicento, my wheel studs are tight as fook in the hub and to make matters worse, they're not quite 19mm. As such, I can't get the disc off!

Are they 18mm?

Any quick tips for me? I've left the back soaking in WD40.

HELP!!!!

Cant you get your disks off without taking the threads out? I can on mine, but then i dont have a lip at the end.

Anyways, if you want the get the threads out, use 2 open ended nuts tighten them together against each other, then undo the one nearest hub. The second nut will stop it undo-ing, thus the thread will then undo...

If its the Fiat fitment studs as fitted to the abarth models it is a 19mm bolt that holds the studs on i know as i just took off a full set of them at the weekend on Emma's old cinq and put them on her turbo cinq as well as change over the Putno GT brakes.

you will need these off as they bolt to the hub as you know and actually hold the disc in place.

i would say plenty of WD40 on the rear of the hub where they screw and then try again and on refitting make sure you have acan off brake cleaner at hand to clean all WD40 off the brakes.

Well I didn't know that but I do now! Thanks :D

How does that affect the change to punto GT discs as on the Bravo/a they are held onto the hub by 2x 12mm bolts with long heads for locating the road wheel. Do you just leave these off and the road wheel bolts hold the disc in place?

makes no differance to the Putno GT brakes as you may have noted i said i fitted them along with the Putno GT brakes on Emma's car, you still have the 2 12mm bolts but they are flat headed & TBH they are redundant with the Fiat studs, you do not need locating ones as you have studs :)

the Fiat studs are a great idea as you therefore do not need a stud extractor to remove them just a 19mm spanner. It difficlut to explain but a normal stud has a little smooth section in the middle so when you bolt them up this stopps it being bolted straight thro the wheel, but the Fioat ones have a 19mm bolt so you just bolt that up, it therefore hold sthe discs in place at 4 points rather than the 2 12mm bolt sthat you refer to.

I feel a request for a piccy coming up..... :p


I take it the Sei's normally have the 12mm bolts and bolts as standard but changing to these Fiat studs does away with the need for the 12mm bolts? Go on.. Help a big fiat owner learn about the lil ones :D
 
yeah on Cinqs/Sei you normally get the 12mm bolts one of which is a locator thet other is normaly just a retainer, on the Abarth models as they have a 10mm spacer on eth front it a stud conversion all round with Fiat fitted studs, so you do not need a locator, you have 4 studs it couldn't be easier to fit wheels and as they have bolts on them they hold the disc, but Fiat do fit two flat head 12mm bolts which is probably more to do with holding disc inplace if you remove studs for maintenace of some sort but IMHO they are not needed.
 
Finally got them off, the one I'd started on I think was factory knackered on the thread, I used a ring spanner, a big nut and my locking nut to stop it slipping off. Job done.

Took an hour to do one side, then only 30 minutes to do the other including freeing sticky calipers. Brakes are much improved now with OMP discs & pads - woohoo!
