I've gone down the Sonora grade in a Silverado with 22 year old brake fluid. I wasn't towing, but it was very hot out and in general yes the brakes were hot when I checked at around 4000 feet.

I wonder if some YouTuber has done some experiment to see just how bad fluid had to get before a typical driver could notice.
