Technical Rusty rear brakes

[coolbumble]

Hi
Friend of mine has just exchanged her 2011 Fiat 500 1.2 lounge for 2015 Fiat 500 1.2 sport 1700 miles . mileage etc confirmed. When trying out the vehicle they said needed to be driven a short distance to clean the brakes as the car had been standing !! It did. However we both have fiat 500 s and never happened to either of use even after leaving the car 3/4 weeks unused
Before delivery they agreed {Fiat Dealership) to check it out and confirmed it was the rear brakes and they had now oiled and corrected it .
The car has 11moinths Fiat warranty left.
Any one else had the same problem with rear brakes after such a short time ?
Regards
Ian

500 rear brakes get such little use in normal driving it does happen. I have also seen the shoes delaminate.

When we bought ours the front discs were appallingly rusted, though a older car it too must have sat somewhere near to the sea I think for quite some time.
Discs on the rear of yours? if they are bad insist on the dealer to replace them.

The friction surfaces of the front discs and rear drums are susceptible to surface rust. Some friction material seems to promote it more than others, so the stuff they're made of must react with the disc a little. I've got Pagid front pads and the discs seem to rust quite quickly. Original discs, which didn't seem to rust so much with the original pads.

My rear drums do occasionally grind a bit too.

Damp weather, rather than wet, will bring surface rusting quite quickly. If the car is used every day, you'll hardly notice, but if, like mine, it is only used once or twice a week, it will rust noticeably. The first few hundred yards down the road it is making a lovely scraping noise, light brake applications will rub it off. When I wash the car, next day always has lovely orange discs, to match the car.

If the dealer has had the car sitting for a month or more, they are very likely to be rusty. Driving it will sort it, or removing the drums and cleaning the surfaces with fine abrasive paper will also work. Hopefully they've not actually 'oiled' anything on the brakes.

That's what happens if you use unpainted cast iron components in the UK climate. Easily solved by painting them, but you really need to do it when they're brand new.

Note, if you wash the car, don't leave it days, with discs on the rear without moving it, I've found if I do the above and leave my Mazda a few days the brakes pads are stuck to the discs, they eventually will release with quite a bang.
