Hi I've owned my at about 9 weeks and absolutely love it! BUT on every wheel there is rust behind it??? We've contacted the Renault garage and been told it "happens" on some cars - it's a 14 plate and I'm a bit miffed that it would appear on a car this old?? Is there anything that I can say to the dealership? Because I'm worried that when I come to sell it that no one will want it due to the rust!

What do u mean behind the wheel? Are we talking on the wheel? On the brake drum? On the rear of the brake drum? On the drive shafts or other suspension parts?

That's the calipers, a lot of cars get surface rust on the calipers, the more expexnsive cars have painted calipers to remedy this.

It's another one of the cost saving measures that helps keep the price of our cars low.

Get a tin of high temperature paint, a wire brush, and a few hours spare time ;)

I am a female so please beat with my "lingo" haha but behind the alloy wheel it looks like where the brakes are is rusty on every wheel? It's a 14 plate and I've owned it for 9 weeks it's like it was covered up when we bought it and now it's been washed it's suddenly appeared?? The dealership are saying "it happens" ???

I think they all rust there, I remember the first time I noticed it on the first car i had with wider gapped alloys, that was on a brand new Ford, I took it back in panic and we looked under a few others in the dealership and some where powder coated in places, some weren't, luck of the draw, I'm guessing that's where steel wheels with trims become more appealing to hide it.
have a look underneath there'll be alot more, but it's usually cast iron, it'll take a long time, decades at least for rust to eat through it enough to cause a problem, we had a fall pipe outside our old house that must have been 50-60 years old, hollow, rusty, but still watertight.

Is that surface rusting too?? X really appreciate your help
Yes, perfectly normal. Unsightly, perhaps, but nothing to worry about. Bear in mind, your braking components are under immense frictional stresses, and produce intense heat. They're also mere inches from the road surface, so when it's wet they are continuously getting soaked and flash-dried. Normal paints simply don't stand up to this sort of abuse.

Next time you have it out in the rain and park up, pay particular attention to your brake discs (front wheels). The surface will be bright and shiny. Leave it a couple of hours and when you come back, these same surfaces will now look like something lifted from the wreck of the Titanic! But after a short drive and a few applications of the brakes, they'll be back to shiny shiny again.

As RD says, you can get specialist high temperature resistant paint for use on these parts; I would think only high-end and performance car makers would use it as standard.

Perfectly normal it's just surface rust as said. Those parts get heated and cool a lot and get wet and dirty and this creates surface rust. Expensive cars paint with very tough high temp paint but cars like ours keep cost down by not painting. My rear drums are very rusty looking as all the basic paint is off them now and I am thinking of painting them black again.

The rear brake drums can be painted with the same high temperature paint too, I usually give the driveshafts a rub down and Hammerite them too, but it's all just surface rust, and not actually necessary to do anything,

Unless you've got mild OCD like me ;)
