2015 Tundra - Brake Maintenance Question

I'm looking to replace my brake pads on my 2015 Tundra Crew Cab. It's at 70K miles and I want to get it done before causing any damage to rotors. 1) I got some highly reviewed Power Stop carbon fiber ceramic brake pads. Anyone have any reviews on here I should know about, good or bad? 2) I was going to do a brake flush, but because I found several threads about ABS that i didn't want to get into, I called the dealership to see what a brake flush/bleed would cost - they said they do not do them there and the maintenance does not recommend a brake flush unless you are having issues. I thought the whole point of "maintenance" was to prevent "issues". Any thoughts on that as well?
