Hi all! New here and looking for help (I did check previous threads and couldn't find my question, but do reroute me if I missed it)!

Anyhow, I own a lovely little espresso brown 2012 Fiat Pop that I love so much I brought it with me to Sweden when I moved from California two years ago. Well, fast forward two years and I need to change the brakes and I am having some troubles. I bought new pads and rotors and had them shipped to me, and they were totally wrong despite me entering the correct vehicle specs on the site I used (a German website). I thought maybe it was an issue with getting parts here to fit the US version, but on some further digging it appears that there is something else going on. Does anyone know if multiple caliper assembly models were used in 2012 for the US Fiat Pop? The rotor I got was also slightly smaller than the one I need to replace, and was solid (the ones currently on the car are vented). I am confused and can't figure out what I need to order! Any help appreciated! Thank you!

Welcome, do you know the diameter/size of you need?
As a last resort simply go to the Fiat dealer with the vin/chassis number?

The 1.4 here has 257mm x 22mm vented discs, the 900cc uses 284mm x 22mm vented(does vary between years), if that helps.

I believe the US Fiat 500 was made in mexico, and as a result would use parts from what ever suppliers are local to that factory.

Best place to start would be to look for the model number/part number of the calliper, for example the ones on the back of my Punto are Bosch Calipers and have a specific model number, I recently needed to replace one of the sliding pins a sthe gator has split letting in water, I gave the part number to a supplier of calliper parts and he was able to send the correct pins gators and bolts to over haul the calliper.

A company like that should be able to tell you what pads you need and may be able to advise on the discs you need.

Worst case scenario, have you considered swapping the calipers for European spec replacements.

I wonder if your Cali 500 had vented brakes to cope with the local temps where as the E.U. cars have brakes designed for a broader spectrum of temp ranges.

There may be other little things you’ve not considered like the type of oil you should use.

I have only visually confirmed the front rotors and they are 257 mm vented. Can I assume the rear are the same? Was thinking of removing to be sure?!

Hi to Norfolk! I have family in Norwich and have spent many summers over the years in North Norfolk!

The car was made in Mexico, yes. I hadn't thought about switching out the calipers, but maybe I should consider that. I found a rotor that seems to match the front one (From website bildelaronline24, Champion part 562178CH, sorry but I can't post the direct link here because I am new, I guess!) but does not match the OEN that the German company just sent me back for my rotors according to VIN (that they cannot supply) (OEN is 5154237AA). I am scared to order the ones I found, even though they seem like they must be correct, because they do not match the OEN. Thoughts?

Never assume anything, rears are generally solid on "normal" cars

I would search eBay USA for the part number Fiat fitted to your car... work out the part number of matching parts (e.g. "Bosch 22233344" ) and then search for that component from your favourite car parts website.
