Step 1 remove driver's side tire - easy
Step 2 remove caliper - easy
Step 3...Took me 1.5 hours to get the front caliper carrier bolts off
The rest of that side went smoothly
Everything was going nice and smooth on the passenger side until it came time to put everything back together and now I'm fighting with the caliper piston that doesn't want to retract far back so I can get things back on with the new pads...
I'm losing daylight (sitting here typing away) and it's getting cold. Looks like this will be another #fail
Goddam salty winter roads...

I had the same problem recently and I even used a 1" bolt to push the Piston in!
I ended up having to sand off about 1.5mm total from the two pads before I could replace the caliper.
Belt sander would have been better but I used a flap wheel and right angle grinder.
Brakes squeaked like a bus for a week or maybe two but they are worn in now.
also: I often can't get the caliper bolts out with an impact tool because the necessity of using a wobble extension acts like a torque stick.
A box end wrench and a hammer works every time. A socket and breaker bar also works but the offeset doesn't love to play nice with hammer some times
