Surface rust on new discs

They can't fail an MOT for corroded or worn discs now, they only fail if your car fails the brake test or if the discs are cracked or broken.
 
Not on new discs and pads, they need to bed in and triggering abs will probably glaze the pads or worse warp the discs.

Don't worry about them, the rust will come off and the brakes work.
I severely doubt you are going to warp the discs by doing an emergency stop!!

And some pads come with instructions to hammer them a few times to bed them in, whereas some say just drive normally. Best check the booklet :).
