I change my brake fluid in all my vehicles every 2 or3 years. On my Lexus, I did it every 2 since the master cylinder/ABS unit was over $1000 And it was known that changing fluid increases its life.
It's cheap and easy.
Just draining the master cylinder and putting new fluid in it is kinda ridiculous. It's not the fluid that is going to be causing corrosion in your system.
If the brake fluid (along with the water, moisture, and contaminants that are emulsified within the brake fluid) doesn't cause the corrosion, then what does cause the corrosion? How do you remove it? What's the point of changing the brake fluid in the first place?
Most would agree a total brake bleed/flush is the most effective maintenance approach. However, to say anything short of a total brake bleed/flush is "ridiculous", well, that sounds like someone who may have the luxury of excess time and/or money on their hands. For the rest of us, I think common sense says maintenance doesn't have to be all or nothing to be effective.
