Alright, I bought a set of hawk pads and I started to install them today on my pass. side rear. I can't get the piston to compress in order to get the caliper over the new pads. Is there a trick? Is there a special tool that will compress the piston? If so, where do you get it?

I don't have an exact answer for you but I remember reading here recently that the piston is supposed to rotate as it compresses, so you aren't supposed to throw a regular c-clamp on there or you'll break something. Hopefully someone else has the proper method for actually compressing it.
Yep I just got out my Haynes manual and it says to rotate the piston clockwise with a brake piston tool or needle-nose pliers, and you should screw it in all the way and have the 2 notches in the piston lined up vertically.
The first couple of turns are a bitch..but after that it's easy.. The first time I did it I tried the c clamp because I didn't know.. I turned so hard that the damn c clamp broke in two
I personally would not use needle nose pliers. You could slip and poke a hole in the rubber seal around the caliper. I got an universal tool from Autozone for like $6-8. You have to apply preasure while you are turning the piston clock wise. I found out that even tho you think you may have the piston "fully seated", if the caliper won't slip on the pads/rotor w/o a struggle, you still don't have the piston in far enough. I gave up a couple months ago after nearly two hours, but am going to give it another shot this Saturday.

Well, the right tool makes all the difference in the world. Went to autozone and bought a brake piston tool. It is actually a rental tool...you pay $35 and you can either keep it or return it. I rented a pulley puller from them before too.
Once I had the piston fully backed out, the caliper went right over the new hawk pads!
