First brake pad replacement on a 2015 sedan: rotors EPB piston compression tools

[TylerH]

I'm planning to do my first brake pad replacement on my 2015 sedan this weekend, as I'm starting to hear a slight squealing and the pads look thin. I've watched a few tutorials and feel confident about the process, but I'm unsure about a couple of specifics. Do I need to replace the rotors as well if there's no major grooving or vibration when braking, or can I just have them resurfaced? I'm also confused about the proper method for compressing the caliper piston, especially since my car has an electronic parking brake. For DIYers who have tackled this job, what tools beyond the basics were essential, and what's the most common mistake to avoid, like forgetting to lubricate the slide pins or improperly torquing the caliper bracket bolts?
