The brake caliper should be tight.

The bolts are what tighten it. Remove it and check to make sure the bolts aren't stripped part of the way and not allowing the bolt to tighten.

Go to this link and you will watch a video on how to replace brake pads. You will see what needs tightened.

I screw the two bolts out they don't look like they are stripped, I don't see what need to be tightened, do the brake pads help to keep the caliper tight.

No. What part of the caliper is loose? When you tighten the bolts, does the mounted part of the caliper get tight?

The center of the caliper is on a slide and has to move. However, the part that is bolted should be secure.

That is correct. It should slide on those bolts. However, the caliper piston should remain extended so there isn't play between the rotor and the brake pads. Thus, nothing should really be "Loose"

Can you upload a pic for me to see what is loose?
