Im rebuilding a car that has been stood for sometime outside...

The disks have quite a lot of surface rust on them, doesn't appear to be any pitting or flaking though....

What is the best way of cleaning the disks up?

Im tempted to leave the disks on the hubs and run some sandpaper over them, starting course and ending with fine....

Anyone else tried any other methods?

Wire brush then just take it for a drive with your foot on the middle pedal

Thos plastic paint stripping discs for the electric drill work quite well but you have to get them at the right price B&Q charge way over the top for them. -- some tool shops sell them for £1 or less.

have heard leave them in vinigar over nite is good never tryed it though

I'm selling some calipers and discs on eBay.

I cleaned the discs up a treat using hammerite's 'dip' concentrate.

Just add water and immerse overnight.

Want to see the difference?... check out my advert HERE in the for sale section and then compare to the photos on eBay (link provided in the for sale thread).

Hammerite price £8.99 from Halfords.

sand paper to take the most of it off, then drive it.
if the cars not ready to be driven yet, and the discs are jammed into the brake pads, take the calipers off and leave them for now.

in summary, if you can drive the car, drive it and the rust will come off, if its not drivable, why worry about it now?

Shirley this is a job for electrolysis?

I used the tool, it worked well.

Electrolysis, only non intrusive solution IMHO
