2013-14 F-150 6cyl

Anyone towing w/a 13 or 14 F150 6 cyl. NHTSA is investigating a several reports/complaints of a problem with Master Cylinder loosing fluid. This issue causes partial to full loss of braking w/little to no advanced warning. Should be a recall coming soon. In the meantime be careful and keep an eye on your fluid levels!

I'm assuming this 3.5 V6 they speak of is in fact the EcoBoost since the base model V6 is a 3.7L. I'll definitely keep an eye on this, however I don't really see how other engine model trucks aren't affected as well... You'd think the brake system would be the same regardless of engine. Perhaps it's a matter of the EcoBoost operating under both vacuum and boost conditions and the brake booster needing a different design to accommodate this.

I'm towing with a 2014 F-150 3.5L with EcoBoost. Haven't had any problems with the brakes, other than some squeaking at less than 10,000 miles. I'm due for an oil change, so I'll have them check that when I bring it in for the oil change.

I agree that it seems likely all F150 models would be affected, not just the V6 models, but so far the news reports have been very specific that it's only the 6 cyl. models. Believe me, I'm paying attention!

As long as you keep an eye on your brake fluid levels you should be fine for the time being. Ford may release a TSB once the investigation is complete. I talked to my service manager and he has only seen 1 case of failure so far.

Thanks, I will keep a little closer eye on the break fluid levels. I recently got the "extended warranty" notice for the break vaccum pump. I've had mine replaced 3x now, so glad they're going to continue to replace it for me haha.

It is my understanding that the '11 and '12 models use an electric vacuum pump to provide vac to the brake booster when under positive pressures (boost) and because of ongoing problems with that pump, they switched to a more reliable mechanically driven pump in '13 and up.

Yeah, you're right. I just realized this post was for 2013 & 2014. I have a 2012, so I am stuck with the crappy vaccum pump but no break booster problem... 6 in one, half dozen in the other. Fix one issue and create another, isn't that exactly how it work? Ha!
