To update on the brake failure... The truck is still in the shop (Santan Ford in Gilbert Arizona) awaiting parts coming out of Northern California. They have provided a rental car even though i don't have the ESP plan. To generally respond to some of the other posts. there was no redundancy, or 'some' braking from the front or rear brakes. The truck would roll in if in gear and the pedal to the floor. Since the failure occurred at 5:00 am, traffic was light, the dealership 3 miles away, so using the emergency brake i dropped the vehicle off at the dealership. Being a Reliability Engineer in the Aerospace field i can only account this to a quality defect, or whats called an 'Infancy' failure' on a weibull curve. The MC and Booster should see this type of failure for at least another 150K miles. Usually i dont post to Forums, or other social media, but in the name of safety thought i should at least get the word out because when that pedal goes to floor your heart skips a couple beats..lol

Well.....now you heard of it!! FL610 is my son and I guarantee you that between the two of us we have owned four SCREWs in the past three years and it happened...call the service manager at SanTan Ford and ask them....maybe they are in on the troll hoax.....


Just hope none of the rest of us out here have the same issue that you are happy to make light of....just because you never heard of it.....that is why he posted it so you might be warned that it IS happening....maybe you should acquaint yourself with the use of downshifting and using the emergency brake instead of wasting time on a troll hunt.


Here is Ford email concerning this issue....they took it VERY seriously....can you say RECALL BAIT....not to mention the legal costs had someone been injured or lost their lives due to this failure!!

I thought you were correct, as none of this makes sense and have never seen it (and doing this over 40 years have to go back to the 60's to find single resivoir MC units, but they are now providing what appears proof.....have to see what happened as I am totally stumped on this one...

Only time in the past 10 plus years my foot ever hit the floor braking was when my caliper froze. I didn't realize my front passenger caliper froze and I was dragging my brakes. Thus is boiled the fluid and to the floor it went.
The other time was my mistake. I was rebuilding my master brake cylinder in my 1978 ford. On the master cylinder piston there is 2 washer like washers. Installed them backward and as I tested it, whoops. Just had to break everything down and reverse my mistake.
Those cars in the 70's were so easy to fix thank god.

[MENTION=181708]fl610[/MENTION], thanks for posting ref. your problem. Please do keep us updated as one never knows if they will have the same problem, but I hope no one else does. Knowing the cause could very well help. Hope they get you rolling soon.

ive driven a couple vehicle that had no brakes, and that was so i could wash em before they went in the shop and one had lost the master cylender, quite literally lost it, somewhere in the mine. and you could put the pedal to the floor and have nothing

I'm glad I was wrong but not for this very unusual brake system failure, I've been wrenching since points, condenser, and carb's were the norm and have never heard of a catastrophic failure of this type.

I have mostly old vintage 'Vettes in my garage and like you never heard of such an issue, even with the antique stuff....my tires have production dates in Roman Numerals (LOL) and all the parts are mostly original 50+ years old, but this is new to me.


I would like them to explain how such a failure could occur in such a new vehicle unless it was faulty manufacture of parts used coupled with no redundant systems!? We raised the flag to make sure someone at FMC looked into this "impossible" scenario and got to the root of what caused it an how many other faulty master cylinders might be out there waiting to fail......Personally I hope none, but we did not want it to just be handled as a routine part failure and replacement by the dealer...this is potentially up there with sudden acceleration issues!


You can bet I am glad my son and fiancée were not cruising down the freeway when it decided to let go.....I believe he said he got the "low brake fluid" indicator and immediately wham, the pedal went to the floor.....mucho scary huh!?


Hopefully a one in a million fluke, but after the Korean Ferry disaster it turns out that there was similar issue in other boats modified in the same manner, like a sister ship that has been pulled from service.....the Japanese had a similar ferry sinking a while back but, due to crew action etc no lives were lost and they found cargo restraints failed amongst other issues and no more disasters after drastic steps were taken there.....too late for the poor Koreans.


We will keep you posted as we get more word....the truck may be back online Monday or Tuesday.....will see what parts need replacement and after system evacuation if other problems arise.

Very scary, glad you didn’t get hurt.

I have seen this all too many times and have had it happen to me more than once. Let me tell you, it is an extremely uncomfortable feeling when that pedal goes to the floor and you don’t even slow down.

It is not really that uncommon on old vehicles that have moisture in the fluid. The moisture causes rust and crud in the master cylinder bore. The rust and crud isn’t a problem throughout normal stroke. But, when extended stroke occurs due to a malfunction or manual bleeding, the rust and crud can damage the seals and the pedal goes to the floor without building pressure in the lines.

Also, I currently have ‘80s vintage vehicles that have single reservoirs but have valving that can isolate sections of the system to avoid complete failure in the event of a major pressure drop in one section.

This was likely an odd isolated failure due to a defective component or contaminated system.

Again, glad no one was hurt.
