I was changing my front brakes yesterday. On the front passenger side I had removed the bottom caliper bolt. I was putting the new pads on and the calliper fell off the top. The caliper grease pin came out. Is this ok? I would think so cause I dont see how the grease pins are really held in.

 

That sounds normal - once the caliper is pulled off and out of the way - basically, the only thing holding the slide pins in are the rubber dust boots.
