My Ford Puma rear discs are suffering from repeated corrosion, what could be the cause?
I bought my new Puma in October 2020. At the two year service, I was advised the rear discs were badly pitted and corroded, and as I noticed some uncomfortable braking, I had new rear discs and pads at a cost of around £500 about seven months ago. As the car had only done around 7500 miles, I argued this should be done under warranty, but lost. Ford did give me a £100 voucher as a goodwill gesture though.
As the car has just had its first MoT, I advised that again, the rear discs have some corrosion. I use the car a few times a week, and whilst I do live near the sea, surely discs should last longer than this? The front ones are perfectly okay.
What's your advice please?

A degree of disc corrosion is normal but this is usually worn off when the vehicle is driven. It seems unlikely that there is a fault with the discs themselves as this has occurred with two different sets, so it seems most likely that it is a combination of the environment and the frequency of you driving the car that is causing the discs to corrode prematurely.
Unless you are able to park the car in a garage on a regular basis, it may be that a regular longer journey is required to enable the discs to be cleaned by using the brakes. If you are usually driving in town it may be that you have no need to brake hard enough for the rear discs to engage sufficiently, so braking from higher speeds and for longer periods may help.
