Any tips on cleaning up RuSty BrAkE DiScS?

Love the new look forum

I have just picked up my new motor, a 2000 x plate 2.0 petrol at a good price. It has been stood around for about a month and the rear discs have gone a bit rusty, causing them to grate a bit. The rust isn't too bad, and its not pitted or owt, any tips on cleaning them up?

if its drums, a good ol wire brush to them's the best bet..

if its discs, brake cleaner

Oiled emery paper, apparently.

Or get them skimmed... Yeah, right.

if it were mine i would just use the car and just the use of them would burn the rust off....and keep an eye on them as to how they're doing

if thats of any use to you

I'm not sure how scored the disks would end up. In days of old you could get harder pads for doing this sort of thing.

When me and my dad took the back brakes on my D9 apart we found one of the sliders has siezed and the outside of one disk was a mass of corrosion. As they were going on the D8 to sell it I wasn't bothered but my dad thought it would be too easy to see through the alloy so he disappeared off into my workshop with some emery paper and a can of light oil. 15 minutes later he reappeared with the disk, no rust, no pitting, amazing.

Thanks for the tips guys, they have cleaned up quite well.
I have noticed that the backplate is rusty too, and being so close to the discs, causes a right rumpus! I had to bend the backpate away from the disc to stop the noise!! Crap design1 I remember I had the same problem with the rear brakes on my 406 v6
