When you say brake flush do you mean sticking the vacuum tubes up the brake lines and sucking out all the brake fluid?
Cant you just drain and refil the brake fluid from the master cylinder resouviour? I know you would have to do it a few times but i mean Im definitely not capable doing a brake flush but i know how to drain fluid from the res under the hood and refil with new. And over time itll mix with the rest.
Thats what I did with my power steering fluid. I had it flushed a year ago but just a few months ago I used a suction gun, sucked out the PS fluid from the PS res and refilled with new.
For a well-maintained, no-leaks cooling system, the color will not change noticeably. There may be some color change due to a slight bit of corrosion and heat, but nothing I've ever noticed. A drain and fill of the radiator every 2-3 years, after my first drain at >100k miles, is what I meant, also.
There will be some communication (mixing) between the brake fluid in the reservoir and the rest of the system, but bleeding the brakes through the caliper zirk fittings is the only way to ensure fresh, "dry" fluid in your calipers to minimize corrosion and the chance of seizure.
