Put a smaller less noisy squirrel in there.
I'm a little stumped. I would have said to check both the wheel bearing and brake system as you did. Having replaced both I'm kind of scratching my head. I'm assuming when you changed brakes you mean the break disc. It may be the pads. Anti squeal on the back of the pads might be in order. Or if the pads have the metal extension most common pads have to alert you when they are getting low has some how gotten bent and is in constant contact with the disc that may be causing it.
