My oldest daughter's May 2019 Leon Cupra has only done 10K miles from new, but now I see that the rear discs are black with corrosion and badly ridged - is this what any other people are finding probably due to lack of continuous use?
I scanned her car on Sunday prior to it getting its second service today and checked the discs then, initially I thought that the driver's side rear disc had turned blue or bluesih as she has just returned from a trip down to Canterbury (and back up to Edinburgh). She later confirmed that neither side gets warm or hot when the car is being driven around, so I worried less as initially I thought that it was due to the rear brakes partially seizing/dragging.
I'd think that I'll be suggesting that they get replaced before its first MOT and probably I'll fit Pagid discs and probably Pagid pads on the rear. The front discs are perfect so no worries at that end.
In the past I've found that any replacement discs stay in good condition longer than the original factory fitted ones, well from VW at least.
Finally, yes I know if you look at cars in any car park, the rear discs probably don't look to be in good condition, lots of that will be due to most cars not needing to hand over very much of the braking effort to the rear discs, so they don't suffer much from wear which equals they do suffer more from corrosion!
Edit:- by the way, my 2011 Audi S4 at (gulp!) 24.5K miles, has nice shiny front and rear discs, my wife's 2015 VW Polo 1.2TSI 110PS at 34.5K miles, has nice shiny front discs but the rear ones are slightly marked with corrosion.
