Are you supposed to cut it out and somehow try to stick it behind your wheels where the calipers would go? The drawing shows the brake pad on the inside and the dotted line goes along this inside pad. The disc is what mounts to the wheel hub, though. So if you just try to put this cutout on the wheel hub, you'd be wrong cause now you're adding in the width of the inside pad. Is there something else you're supposed to do with this drawing?
