Brake problems Options

[Insanity-74]

I have this awfull clicking noise that seems to be coming from my passenger side rear wheel,(the left side, my cars RHD remember) it only happens at slow speeds, or should I say its only noticable at slow speeds, it coincides (sp) with the rotation of the wheel, it dosnt happen all the time, its worst early in the morning, on right turns and when the car has had chance to warm up, it dispapears when light pressure is applied to the foot brake but not when I pull the handbrake on. I have checked th back of the studs for clearance..everything is OK, I have new pads on, new discs, had the wheel bearing changed, had the handbrake shoes changed, had the oil in the diff changed. What on this earth could it be? I`m at a total loss.
