anthonyb: There are two rods (not shown in your pics) that keep the pads in place...the holes just above the piston (in the pics) is where they slide in...actually the ends are serrated and you have to tap them in (or out) when replacing pads.

I guess this all depends on what year we're are talking about. This is all pretty fuss-free on the 93 model...
