Brian S: Yep, the buttons are different on the blade-brake version introduced late in the 1x8/9 series to meet OSHA requiremnets. What you see in Charlie's photo the the brake disc. The brake pad is the circular piece attached to the throw-out arm (or at least you should have one there). It's easy to see in the service manual if you have or can get to one.
