C-Clap or piston compression tool... either one. And some basic hand tools; nothing too complex.
I don't recall if the bolts are standard hex head bolts or allen key bolts. I'm leaning toward standard hex head if my memory serves me right. All metric.
So, if I am correct; Metric sockets and combination (open/box ends) wrenches.
If you're doing the rears, it's advisable you get a tool; for about $15-$20 napa will sell you a metal disc that goes on the end of a 3/8" drive ratchet. This is all you need; they sell the ones that apply pressure for you as you turn it, but a monkey could press down on the ratchet as he turns. And remember, on the back pads there are nipples that index into the piston; two, they fit into the triangle cut outs on the piston that the tool fits into. Easy stuff.
And last but not least, it's not a bad idea to throw some brake anti-squeal on the pads... might not need it, but if you do then you'd have to take it all apart again; who wants to do that? There's some good stuff that comes in a clear bottle with a dispenser tip and the compound is pink/red. Just clean up the caliper and piston, spread a medium coating on the BACK of the pad, put the pads into the caliper, caliper on the car and you're set.
Good luck!
