rubbing noise when starting off

[missmouse]

Noticed a slight rubbing sound when starting off. Goes away ( or cant hear it!) once speed gets up a bit. Checked brakes as thats what it sounds like - rusty dicts or worn pads) but all ok.
Its hardly noticeable but its bugging me!
Any ideas?

Pads can trail a bit on discs and make a noise. The car brakes/pulls up straight and no other odd noises? You could offer a hand up to each wheel after a decent trip and if you can feel heat at a wheel you might have a slightly stuck piston.

Ive had wheels off & discs look fine. A little rust around edges. Brakes work really well.
Noise from rust Ive experienced before but it usually clears after a run, this doesnt.

Just another suggestion as I've had this issue with my old 2011 Audi S4, on my car it was happening once per wheel rotation, and it turned out to be rust building up on the ABS speed sensor ring, and the ABS wheel speed sensor eventually failed - it had inherited the task of working as a scraper cleaning off the rust building up on the magnetic ring. On that older age of car, the individual magnets are exposed so can end up rusting, on much newer cars, the magnetic ring is potted and so does not have that weakness, but, it has been reported that rusting under this potted reluctor ring, can cause it to lift - and it's back to what happened on my old Audi S4 - ie eventually a failed ABS sensor due to the sensor potting having been worn through and shorted out its innards!

As I said at the beginning, only another possibility.
