B7 S4 brake change.

Morning all.

I am going to do a brake pad and rotor change. As I was looking through the Bently manual I saw the note that replacement pads have an arrow and the pads need to be installed in the direction of rotation. I am swapping out the OEM pads for Hawk HPS. The Hawks have no arrow and look unidirectional in their shape. I am assuming then that the Bently manual is only referencing OEM pads when talking about the arrow and direction. Anyone use the Hawks and run into this?
