I have noticed recently when I go from throttle to braking in my ST170 I get the tiniest of movement on my steering wheel.

It's not like a warped disc where it vibrates, and I can't feel any wobble in the steering wheel.

It's just the slightest of movement in the steering wheel, but it's just the once, and only a few mm ?

The discs and pads look o.k.. just wondered if it could be a bush ?
