rust on brake disks
Discussion
All my cars' brake disks get rusty. This I assume is because I do a shed load of wet miles. (Plus I live 20 yards from the sea). The V8 disks have started already and I've had it less than 3 months.
Is there some way of getting the rust off every 6 months or so to stop the problem getting out of hand?
Is there a product?... or can the dealer do a proper job on a service?
Ta for any help.

I suspect the sea air is the culprit. Have you a timber framed garage ...?
When I bought my tt the brakes had to be skimmed they were so ineffective , the previous owner (no criticism ) garaged the car after washing it allowing water to settle on the discs.I always take both the 360 and the tt on a run to displace any standing water .

If you get new discs, you can get them painted so that the areas not swept by the pads are protected from corrosion. The areas swept by the pads of course will be bare metal and will corrode gradually, but ordinary driving should clean these up unless the car is left standing for a long time.
I think your main choices are either live with it, get a hair dryer to the brakes every time you put it in the garage or get some composite brake discs!
The outer and inner edges of the disc can as suggested be painted/treated with very high temp coatings but in my experience it doesn't take long for the edge where the pad sweeps to rust, lifting the coating and working it's way out under the coating. If it's not a car you drive regularly then drying the discs after use could be an option but if it's a daily driver then I think you just have to live with it.
ETA - re the doing anything about it every 6 months, sure you can clean it off with some light abrassive without doing any harm.

dont know if its rust but both my old 355 and my merc sl 55 both suffer/suffered from squeaky brakes. in both cases i was advised to really warm up the brakes by using them hard then it burns off. actually takes less effort in the merc as i guess it weighs so much (2 tons). doesnt help if the rust is visable tho in the unswept area

I'm in Central London and after two months, I had rust on some of my wheels...
Near the Thames....?
Actually yes, very near the Thames - it's parked during the day and night at two different spots about 100m from the River...

I just drove normally for 20 mins in the dry and there was still some rust spots, so I drove with the brake lightly on for about 2 miles - stopped and the spots have gone
I've also got rust - quite a lot - on the bit of the wheel behind the brake disks. Could I get them to fix it under warranty?
