Worth it to clean brakes at 15K in winter area?

I will be taking in my Prius for its 15K service, minus the oil change, which I do myself, in a few days. I live in NE Ohio and we have brutal winters with lots of salt on the roads. It's an 07 Prius and has only seen one winter.

According to the Prius service manual cleaning the brakes is not part of the service, just checking them.

Do any Prius owners who live in winter climates have any first-hand experience with their brakes and cleaning them to keep rust, etc at bay since we Prius owners don't use the actual brakes like most cars.

I did find the below advice which makes sense:

"In an area with a lot of salt dumped on the roads during winter snow/ice, it would be reasonable to take the front calipers off, clean and lube the slide pins (Full floating caliper), and reassemble. It would also be reasonable to adjust the parking brake (Cable actuators tend to stretch and loosen over time) and the rear drum/shoe clearance."

Also, I use the parking/emergency brake every time I park the car.

Thanks for any feedback.
