Brake fluid change?
Does anyone here actually follow Ford's recommendation to replace brake fluid every 2 years in an F53 chassis? For decades I've been using synthetic fluid and changing every 4 years. At that interval,...

Synthetic fluid is actually not the preferred fluid to use.
It doesn't absorb moisture, this allows water pockets to form in the brake lines. Which will lead to the lines rusting and eventually failing.
DOT 5 (silcone) yes water doesn't absorb, DOT 3, DOT 4, or DOT 5.1 synthetic fluids, pure BS. these fluids do NOT allow water pockets to form, ALL 3 are very hydroscopic and water will imulsify in the fluid. End result is lower boiling point.
As to when to change, back in 60's and 70's when reservoirs were more open to air, even in 2 years fluid could have lots of water and junk in it. By the 90's the reservoir systems became much more enclosed and fluid didn't degrade near as much. I still pressure bleed every 2 years, but the fluid looks almost new.
