Not at 30,000 miles, maybe every 75,000 miles, or every 10 years.

I did mine at 100,000 miles on 13.5 year old fluid. It did fix the squeaky pedal issue. I used DOT 5.1 (not the same as DOT 5, and DOT 5 can't be used with DOT 3, 4 or 5.1. DOT 5 can't be used on ABS brake systems)

 

I may be wrong, but I think the actual interval is every two years; at least it definitely is on a few other of my vehicles. That works out to every 20-30k miles. Brake fluid is brake fluid, so if one marque says every 2 years and another 10, I’d go with the lower number in today’s world of purposefully and arbitrarily limiting maintenance.

i *try* to address my fleet every two but usually fail on that timetable. 5 engines, 5 transmissions, 2 transfer cases, 6 diffs, etc not counting the dozen pieces of farm equipment, I’m always running around behind the 8 ball.

 

I thought that Ford didn't put in a service interval for brake fluid in the owners manual until the current generation of F-150's

 

Soo.. you don't know. Why toss numbers out there then ?
