help..tracking down a squeak on the drivers side, on the outside of the car

second little niggle has popped up...

When driving slowly (ie parking speed) i get a squeak from the drivers side wheel arch area =

-If i put my foot on the brake slightly, it go's.
-If i turn, it changes in pitch
-it doesn't do it as i reverse off my drive in the morning, when brakes are cold
-it doesn't do it WHEN i brake, only when driving very slow.
-sometimes doesn't do it when hot (ie when out for drive and going slow in traffic)
-if i drive forward and brake slightly at the same time, it disappears for a bit

Could this be a lightly warped disk or something? (ie its catching as it rotates?) Maybe a bit of grit\metal trapped between the pad and disk?

It's hard to tell but the brakes look OK like theres loads of pad left, and its only the drivers side. Car doesn't pull to one side under braking, and the brakes work aswell as i'd expect them to, with no noise.

Any ideas? Maybe worth taking the wheel off for a clean?

Thanks in advance for any advice

Could be a worn bush - possibly upper wishbone. Or could be a wheel bearing issue.

I had this very recently, my dealer replaced the steering rods to fix. they told me it was wear and tear of the bushes etc.

Could be anti-roll-bar as had this replaced 2 weeks ago on the GT.
