How can I prevent brake disc corrosion?

A perennial problem I have had with cars I have owned in the last decade or so is with the corrosion of the rear brakes. My current car, Mini One has just had replacement rear discs and pads for the second time in 30k miles from new. My previous BMW 1 Series was afflicted by continual rear brake problems in its later years. I realise that low mileage can be an issue but is there any preventative maintenance which can be done to protect from corrosion?

There's no easy way to prevent brake discs from going rusty, unfortunately. You could try keeping the car in a garage with a dehumidifier - if you have access to a garage - but we'd recommend just driving the car regularly to keep the discs rust-free.
