I use some anti squeak behind the brake pads. I bought a new little tool that pushes the piston in it works nicely. You could make your own with a piece of wood T nut and a bolt. You also don't need it you can just push and pry with whatever

Don't forget to get sensors for the brake pads if your sensors are tripped

I bought some premium rotors for my rears that are powder coat Grey. Very happy not to have rust inside my wheel anymore
