Just removed the rear wheel in order to do a tire change. Had to struggle some to get the rear caliper bracket to pull back and off the swingarm. After the wheel was rolled away I found a small clip on the floor. It looks like half of a paper clip...the kind that pushes through a hole and keeps things together. I assume it goes on the brake caliper but I don't see any holes in the rearward brake pad pin. Can someone post some detailed photos of the rear brake caliper so I can see where this clip goes?
