Nissan micra not used for a month. Juddery breaks

[Igloo]

My Micra hasn't been used for a month. Since the snow. I just went out in it.

Now it was stuck on the rakes to begin with. Accelerated through it and it freed up.

Now there is a slight judder under breaking. It's dark. I've not had the wheel off yet. But I wonder if its just rust. I hope it's just rust.

The disks and pads are only about 6k miles out.

Any clues?

It will just be the rusty discs mate, and the un-rusty section that was beneath the pads when parked.

50 odd miles with braking will sort it.
