I've never, ever heard of anyone wanting to drain and replace brake fluid, sure add more if they leak or you have to replace a cylinder, but that isn't a thing.
We talked about my position on coolant.
Machines and materials are better these days. They just are.

You fine gentleman are outstanding. I think my thinking might be more old school where you replaced all the fluids every 30k or 3 years: power steering, brake, coolant and transmission. It's just not needed on these sealed systems anymore, is it? So lifetime transmission fluid is a thing, huh?
So I won't touch the transmission or brake fluid then. The brake fluid is super clean and I clean the engine compartment sporadically and this car is garaged.
The coolant looks super clean as well so maybe I will just leave until the 10 year mark like it suggests. It says change at 10 years or 120k miles, and after that every 60k or 5 years.
Here's the maintenance schedule for reference.
Looks like only thing I'm coming up on is spark plugs. The car has electric power steering so no fluid there.
Here’s the suggested maintenance. Everything look ok? Some people claim that they don’t recommend changing fluids as often anymore is just companies trying to cut down on waste and that you should be doing it anyway. Or claiming that they don’t recommend it because it helps buyers think a car is almost maintenance free and they hope you don’t keep your car that long for much of it to matter, or if you do, lack of basic maintenance, since it’s not recommended, will wear out your car faster so you have to buy a new one. (Internet forum talk on these points).
