Rear Brake Rotor Size

[DazzerJ97]

Hello All,



Can't seem to find a definitive answer on this, looking at the brake rotor size on the rear, I come up with two sizes, 282 and 286, my model is a 2.0tdi DSG.



Is there a difference to the sizing for the electric parking brake or?



Any help would be greatly appreciated, should mention my rims are 16's
