I hate that every time it rains or if the roads are wet my break discs look as if they are all rusty Now i know after 5 min of driving and braking it goes away but it just makes the car look so bad sitting in the drive if i don't use it for a day or so. Is this just the way it is? is it just cheap discs? do all brake discs do this?
Yes mate , all , when i get home from a drive for example and look , they are fine! next day they just look all rusted! if i don't use the car for a few days it looks bloody awful take her for a spin and it goes away , obviously braking is cleaning the disc.
Break discs or rotors are made of steel and oxidises (start of rust process). All ferrous metals do this. If available you could upgrade to ceramic discs and pad combination but I think that might be a bit expensive just to get rid of the rusty appearance. I hate it more when the disc hubs start rusting.
If you put the car in the garage when you get home, they stay clean, its only standing outside in the bad weather overnight that sends them rusty.
Also the factory discs have silver painted hub and edges so the rust doesnt show as bad as aftermarket discs which are normally completely unpainted.
