1996 Aurora Rear Brakes

I have replaced the front rotors and pads on my Aurora, now my rear brakes need to be done. I can't seem to find the bolts that remove the calipers. What am I missing? Help!

Thanks.

They're there. I did mine a few weeks ago. There are two pretty big bolts that hold on the caliper. To be honest, when I was doing them, I wasn't sure that they were the right bolts until I removed them and the calipers fell off. It seems like they were about a 15 mm bolt head. Maybe a 17 mm. But there's two of them.
