Default 2011 f150 5.0l.

I saw previous discussions on Ford's vacuum assist problem on the 2011-2012 F150 3.5L EB. When brake warning light pops on while on cruise and brake pedal becomes hard.
I am having the exact same issue for mine with a 5.0L . Ford had no recall for my 5.0.
Would this possibly be the same issue?.

Nope. The turbo engines have a boost assist to compensate for the lack of vacuum available in a turbo engine and this is what was wrong in the EB trucks. Your NA.5.0 has another issue going on. DO NOT DRIVE THIS TRUCK UNTIL IT'S FIXED AND HAVE IT TOWED TO A REPAIR SHOP.

You need a brake booster.
