F-150 owners can’t stop their brake pedals from suddenly falling to the floor. That means they also can’t stop their trucks.
The problem is an empty master cylinder resevoir that’s hard to detect because there’s never any corresponding brake fluid leaks. It’s like a magic trick that no-one finds amusing.
A new investigation hopes to pull back the curtain:
“The no-leak symptom is what makes NHTSA believe the fluid is moving from the master cylinder to the brake booster. In addition to that, some owners told NHTSA that Ford dealers have said the same thing.”
The investigation covers 2013-2014 F-150 trucks equipped with 3.5-liter engines. If the problem is confirmed, it should prompt a recall.
