My biggest complaint when I bought my car!!!! I did manage to get them to replace all the callipers but not the hubs!!! Having said this the biggest cause of rust on these is the use of the wrong type of wheel cleaner, most contain mild acids which damage everything, the best I have found is BMW's own brand which is manufactured by Sonus.
Once rusted though nothing you can do, I even used acf50 but do not touch disc faces
