I have replaced the pads before, and now I have upgraded discs and pads to install, and I like to research any jobs before taking them on. Especially since it's her car. I can't leave it on jack stands for too long or momma will not be happy!!
Can't give you the exact steps. It's been about 8 months since I did mine. The one thing I will say is you will need heat, a big cheater bar or an impact gun. There are 2 - 3/4" or metric equivalent bolts holding the caliper and rotor assembly on the hub and frame. These 2 bolts are installed with lock tite and are a bit@h to remove. Mine required a small propane torch to heat them up and my 1/2 drive electric impact gun. They go back in no problem, but removal was another story.
Remove those, remove the calipers, remove the small "star" set screw in the front of the rotor that holds it to the hub along with the 2 or 3 stud locks and they will come right off.
I would suggest replacing the calipers while you're at it. I know one of mine had a tear in the rubber boot and was causing the top piston to hang on the rotor and not return all the way in, causing premature failure on half the pad.
I think the calipers were about $60 - $80 with exchange and the rotors around $90 - $100 at Advance Auto Parts. They also have a brake tool that you can use to push the calipers back in and a "one man" self-bleeding kit if you open the brake lines to change the calipers. Both work great and are fairly cheap.
FWIW I got it done in about half a day (not counting trips to the parts store for the tools), but it was a frustrating experience and I was dog tired by the time I was done. I'm sure it won't be as bad the second time around if I keep it that long (ceramic pads this time with lifetime warranties).
And, while the brake pads and rotors were worn out and needed replacement, turns out the really bad noise was coming from a bad wheel bearing on the driver's side front that I discovered after the brake job.
