Brake disc rust

[Ricardinho]

dont use my car that often and live right on the seafront so leaving it for a week will leave a bit of surface rust on the discs.

i know by using it it will go away but is there anything that you can put on them to protect them?

Normal mate. When I changed my discs, a tiny bit of rain fell and the rust spots appeared immediately.

aint there some stuff you can coat it with or anything, the rears look buggerd these days, dont get a lot of use with the 4 pots up front i guess

Nothing you can do and its fine.

I really only use my car on weekends, by the end of the road it's all gone. Don't worry about it.

Not 100% but I think those black diamond ones don't suffer from this problem

I can do a 100 mile B-road blast and when I get home my fronts are smoking and my rears are still cold and have rust on them lol

Mine's exactly the same only I never see a nice steel colour...they are permanently rusty orange.

Nothing to worry about...purely cosmetic.

Does anybody know how to increase the rearward bias on a 172 Cup? I think the rears should be working a tiny bit more that they are - Im having real trouble keeping them rust free on the road. Ive gotten to the point where Ive been dragging the handbrake every now and then to try to clean the discs back up.

Brembo do disks with a coating that stops the rust forming, they're an anthracite colour. Not cheap though.

there is no way you'll stop any cast iron disc from rusting
