tC brake problem

On regular occasion when I take a turn and hit the brakes (especially if there is a bump in the road, like turning into a drive)my tC's brakes have felt like they have been grinding. Anyone have any idea what that might be? Thanks.

The first thing I would check is the backing plate on the back of the rotor. If it's close bend it back a little. If that doesn't fix it then take it to the dealer.

In gonna second trd's post. I can not think of any logical brake problem that would only show up when turning. Also sounds to me like something is rubbing
