Possible brake issue?

[flasher]

After a bit of advice about a possible brake issue.

Had the wheel bearings done on the car the other week and since I have had it back I get a strange rubbing noise (sounds low frequency compared to a squeak), when I drive off from stationary. This only happens after about 30 mins of driving and only after coming to a complete stop. Doesn't always do it but it is starting to get on my nerves.
You can feel vibrations in the car when it makes the noise and as far as I can tell it sounds like it is coming from the drivers side at the front.
Also when slowing down using the brake at about 65mph you get vibrations from the steering wheel, this doesn't happen when you are going at 60 or below, it does get worse the higher you go above 65.
Took it back to the garage that did the wheel bearings and they said they couldn't see anything but cleaned the discs and pads anyway.

Could this be a possible warped disc of other brake issue? Will be going to another garage next week so just need some ideas of a possible problem.

Loose hub nut? - You wouldn't think so if they've done a professional change on the wheel bearing.

Sticking calliper slider? - You wouldn't think that would cause any vibrations, but if it's cooking the pad because it's always in contact with the brake that might explain it.

How worn was the old bearing?

If there was a lot of play on the old hub the pads might have worn unevenly, Now everything is lined up properly the old pads will now be misaligned with the disk perhaps!

Car is an 06, first time the bearings have been done.

Will have to ask about the loose hub nut and sticking calliper slider, planning on taking it to a third garage this week.

Strange thing today is that I have had no noise while driving, done one 45min run and another just over an hour, only difference todays and last week is the temperature, been a nice 16-18 today.
