2014 FORD F-150 Service Brakes Problems

NHTSA Investigation PE24010 (or related transmission downshift probes.. Safety Risk: the vehicle unexpectedly downshifts and locks rear wheels, creating an immediate life-threatening risk on the highway. Dealer Response: dealer claimed their "computer doesn't pick up anything," as this helps investigators understand that the diagnostic tools are failing to detect the fault. VIN Number: [XXX] Dealer Record: that Grieco Ford performed the recall update and that the issue persists. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Recall number: 20s31 Statement: “Recall repair completed in 2021. Replacement master cylinder failed. Brake pedal goes to floor. Vehicle not drivable.” Called dealer and they will not fix the safety recall and so I called Ford customer service and they also refuse to fix.

Transmission would downshift unexpectedly causing me to brake and panic, the tool icon will come on dash, speedometer stops working and backup camaras failed, transmission locked up on highway and caused driveshaft to lock back tires. All around dangerous situation

Bought truck on 2/25,. 7/15/25, wife went to store took truck. When she went to stop truck noticed brake pedal was going down but truck stop. Brake light went on so she turned around home. She drove slow when she reached the front of house pressed brake to stop truck brake pedal went all the way down. Could not stop truck with brakes so she hit curb with tire to stop it.I checked brake fluid canister and is was empty.No leaks on street.I called dealer; three days later truck was towed by dealer to their place.I was told master brake cylinder assembly and booster assembly has to be repaired.I paid 1,648.22. I called Ford for any recalls (I was concerned about brakes) I was told that there was a brake recall repaired by All American Old Bridge, dealership I bought the truck from.Repaired was done on April 12, 2017. Recall...

Driving at highway speed when the low brake fluid warning light came up on dash. I managed to get the truck and trailer I was pulling to a safe location and checked brake fluid. I had little braking power. I had brake fluid brought to my location and refilled the reservoir. I inspected the brake system for leaks and there were none. I tested brakes and they appeared to function properly. I returned to the highway and within two minutes I completely lost all braking. The internet reports that there are recalls on some trucks for this problem but my search using my VIN does not show one, but I have the same brake failure described to those reports.

My master cylinder leaked in to my brake booster, so I had to replace both after losing my brake stopping abilities. I received the new parts replaced them then hookup the battery checked brakes turned off ignition. Went back to start engine nothing battery 7.5 volts.. Replaced 250.00 started engine brakes good drove stopped 3 times got home evening sun down brake lights are on, I cant turn them off! unplugged battery. The brake switch was on and broken could not be reset. This is a fire hazard!!! My leads for the positive where hot very hot to the touch, my power was weak on the engine while driving I almost lost my truck over that Brake switch? No where does it say to replace it or why does this happen it clearly is a small broblem that can be a very big one fast!

Transmission & Brakes ... Acting up

I had to do laundry loaded truck jumped in took off got on the highway doing 75 MPH peep peep low brake fluid! Low brake fluid, my peddle was not to the floor but was slow to stop.. no store to fill up brake fluid but an Ace hardware was at my laundry mate which I got 32 oz to fill it was empty. No fluid on ground!?! Did laundry drove 4 miles to walmart almost did not stop! Low brake fluid and it was out! Filled it back up with 32 oz brake fluid drove 4 miles more to home brakes down to floor put in park when stopped at light lucky it was a construction zone all the way home 35 MPH. Got home no fluid leaking out the booster weep hole? because they dont have one anymore? Took master off booster was full of brake fluid had...

They have a faulty master cylinder on the brakes causing brake issues. I was driving down state road 80 after hurricane Ian and a car slammed on its brakes in front of me because a vehicle lost a load off of their tailgate. I slammed on my brakes but I didn't break very well. It was very squishy into the floor and I relied on distance. The brakes gave a little assistance

Vehicle drove fine to work and upon getting in to return home and staring the vehicle, the brake pedal was instantly spongy and low brake fluid alert displayed on dash. There was a difference in 9 hours from when the brakes were fully functional to having brakes were completely out and nonfunctional. Had vehicle towed to local dealership and their diagnosis was "master cylinder is bleeding into the booster" and booster "full of brake fluid." This exact issue has been known and was supposed to be addressed but there have been numerous issues with the new parts installed after the recall leading to subsequent master cylinder/booster failures. Since it has already been "repaired" under the initial recall, the subsequent repair cost $1,300 including diagnostic.

While leaving the VA parking lot, and after breaking 3 times on the way out, as I approached a major intersection, the break pedal dropped to the floor and a low break fluid warning appeared on the display. My slow approach allowed me to stop. Checked the reservoir and it was empty. I walked to the gas station and purchased break fluid, when I returned, I checked under the vehicle for a leak, to no avail. I walked back to the spot I was parked but there was no indication of a leak. I was able to get my car home, and filled the break container intending on bleeding the lines; however, Florida weather forced to wait a day. Today, Saturday, I proceeded to bleed the lines but the reservoir was empty. Again, no signs of leakage around tires, break lines, reservoir, master cylinder. Everything I have searched regarding this...

While driving the brakes failed and pedal was to the floor. No warning light before this happened. Warning light eventually came on after the failure. This was a very scary situation. Vehicle was taken to auto repair shop who confirmed it is a failure of the master cylinder and brake booster.

Either the brake calipers or the soft brake lines feeding the calipers are sticking/collapsing internally causing the brakes to drag/lock up. This has drastically decreased the driveability of the vehicle as brakes dragging is dangerous. Based on internet searches and forums this appears to be a consistent problem with these pickups as this is the most common issue mentioned. Ford needs to address this problem with a recall before someone gets hurt.

This truck only has 35,000 miles on it , so it's a baby! All of a sudden I get a warning light that says there is a problem with my anti lock breaking system. In the 10 years I have had this truck I have never even had the anti lock breaking system engage! The Ford dealership where I bought the truck said I had a DTC C1288. The DTC C1288 on a Ford F150 indicates a brake pressure transducer circuit failure. Specifically, it means the ABS module has detected a problem with the transducer, possibly due to a short or open circuit, where the pressure reading is too high when other inputs suggest a non-pressurized system. This often results in the ESP (Electronic Stability Program) light remaining illuminated. They said if I didn't pay them $3400 parts and labor, my breaks would stop working. This is crazy. The ABS...

Brake pedal goes to floor. Feels like the brakes goes out sometimes.

had a recall on my truck to replace master brake master cylinder on October 2014, my truck lost braking power on [XXX] before I was able to leave my community almost resulted in me driving to a pond with toddler in the backseat. I was eventually able to bring truck to a full stop using extreme force to push brake to the floor. Upon discussion with Ford service representative, it is highly likely due to premature brake booster failure as a result of recalled brake cylinder. Upon further research on Kelly's Blue Book, it states that the brake booster should be replaced "as necessary" as a part of the master cylinder recall but was not in my case. this failure could have resulted in catastrophic failure ending 2 lives and Ford refuses to warrant the repair.

On September 7, 2024 at around 8 AM I was driving my 2014 Ford F150 3.5 L eco-boost and suddenly my brakes failed on me. I was driving and noticed that the low brake fluid light turned on and when I was coming to a stop, it was very difficult to stop the vehicle because I had to press my foot all the way down to the floor since I didn't feel any pressure when I pressed down on the brake. I made it to a parking lot where I put in a bottle of brake fluid, but then noticed that the fluid level went down after a few minutes. My vehicle would not retain the brake fluid and remained extremely difficult to come to a stop without putting myself and others at risk on the public roads. I entered my vehicles symptoms online and found vehicle recall "20S31", but...

The brake booster failed. It is not available. The mechanic replaced it. Because the booster failed the engine was sucking the brake fluid into the intact. This caused the the brakes not to have fluid and the engine to lock up and the engine threw a rod threw the engine. The problem was diagnosed by a mechanic and parts replaced. A brand new brake master cylinder was installed and a new engine is being put in. No it has not. Yes a light came on that the engine was low on brake fluid when it happened.

BRAKES HARD WHEN PRESSED RESULTING IN SAFETY CONCERNS DUE TO STOPPING RANGE. COULD RESULT IN WRECK AND PERSONAL INJURY. POSSIBLE VACUUM PUMP IS PROBLEM. MANY MORE PEOPLE HAVE COMPLAINED OF THIS SAME PROBLEM AND HAD TO REPLACE THE VACUUM PUMP. UNDER RECALL 20V332000 VACUUM PUMP WAS NOT CHECKED. HAVE NOT TAKEN IT TO DEALER THEY ARE HARD TO WORK WITH. IN PROCESS OF TRYING TO GET REPLACED BEFORE DRIVING IT. NO WARINGS OR INDICATORS PRIOR TO FAILURE.

We got the truck out of heated storage after 6 months, and lights on dash came up stating a"Service Brakes" and "ABS" plus warning bells. Took to Ford dealer immediately and they test and said we needed a Hydralic Control Unit as our brakes would not work. In looking this up, other F150's have been recalled, but not our VIN. So we had to pay $3,000 for part and it to be programed. Fortunately it is an extra vehicle for us and we were not caught out on the interstate. I find it interesting that 3 recalls were done for this same braking issue on the F150, but for some reason did not include ours?????

I was driving my 2014 F150 truck with 5.0L engine when Brake fluid level low light came on. I tested the brakes and the pedal was soft and went almost to the floor. I added brake fluid and within 5 miles it leaked out. I had the truck towed to my parents home near where I broke down. Confirmed that master cylinder leaked fluid into brake booster. I can see there was a recall for 2014 F150 3.5L engine for this issue. Called dealer and Ford corporate and was told it did not affect 5.0. Problem is exact to recall and I believe the issue affects more vehicles than listed by Ford. Ford directed me to file complaint with NHTSA.

The low break fluid light suddenly come up, next thing you know, I didn’t have any brake function what so ever. Luckily I was driving off a parking lot. I have to call the tow truck to take my truck to the dealership. The dealer diagnosed, (failed brake master cylinder leaking into brake booster. Inspected brake system and found no external leaks all lines and calipers are dry. Removed master cylinder and found brake booster is full of fluid. Installed new brake master cylinder and brake booster. Bleed brakes) it was a recall for 2014 F150’s for this same issue but dealership said my vehicle was built months after the recalled trucks. I believe if this happened in the highway driving 70 miles an hour could end up in fatalities really easy. I am pretty sure many other 2014 F150 trucks got the same issue.

I was driving about to make a right hand trun on the st where my home is located. Out of nowhere with no warning or any message displayed on my dashboard. The both front tires locked up and automatically reduced my speed. I am thankful for this happening when I was turning on my street to my house. If it would had been a few minutes before when I was traveling at 60 mph and this would accard. The truck would have flipped i was told by a machine that did a house call. He took a look at the brakes and the pads are new the car has brake fluid and the front brakes are still locked. He had never come across this situation told me to see if there are any recalls when I looked up this same problem there are many 2014 ford f150 with the same...

Catastrophic brake failure. Drove truck normally the night before, but when I got in the next morning to go somewhere the brake pedal went to the floor. I depressed he brake pedal 2-3 more times to ensure I wasn't misinterpreting anything and it went to the floor, unimpeded, every time. I then noticed a very large puddle of brake fluid on the pavement under the passenger front tire. Pressing on the brake pedal was apparently squirting brake fluid all over the place from somewhere in that area. Had to have to car towed to a mechanic to fix. I WAS PLANNING TO TOW A HEAVY CAMPER IN A FEW DAYS AND THIS WOULD HAVE CAUSED A SERIOUS LIFE-THREATENING ISSUE HAD IT HAPPENED ON THE ROAD. Ford has had a LOT of brake system failures on numerous vehicles. The mechanic said the right front bake line simply ruptured on its own....

Unexpexted Brake failure had to pump brakes to get vehicle to stop. Would have caused accident in roadway if not for driving it into rumble strip to stop. Scary experience, towed it to get brakes repaired. No weather conditions on road.

The contact owns a 2014 Ford F-150. The contact received notification of NHTSA Campaign Number: 16V345000 (Service Brakes, Hydraulic). The contact stated that while driving at an undisclosed speed, the vehicle stalled. The vehicle was restarted after approximately four attempts. The vehicle was taken to an independent mechanic where it was diagnosed that the timing chain needed to be replaced. The vehicle was repaired but the failure reoccurred approximately three years later. The contact stated that on another occasion while driving at approximately 20 MPH, the brake pedal was depressed, and the vehicle failed to slow down as needed. The vehicle coasted and eventually came to a stop, and was shifted into park, and turned off. The vehicle was towed to a dealer where it was determined that the timing chain needed to be replaced again. The manufacturer was notified of the failure. The failure mileage was unknown.

I remote started my truck and let it run to warm up. I got in and pushed the brake pedal and it went to the floor. I turned the ignition on and the information center said, "Brake fluid low". I turned the truck off, got out and looked under the truck for signs of brake fluid (there was none), opened the hood and my reservoir was empty. I took the master cylinder off and the brake booster was full of brake fluid. I had to replace both, the master cylinder and brake booster.

The master cylinder failed and caused brake fluid to be sucked into the vacuum brake booster. The result is total hydraulic failure of the brakes and a safety hazard. This is a known failure for the 2014 F150's with the 3.5L Ecoboost for which there was a recall. My truck with the 5.0L motor uses the same part.

The truck’s steering wheel locks up and breaks get hard when doing a turn making it hard to stop and almost being in two accidents a service advancetrack light comes on and stays on till truck is turned off.

Brake booster leaking. Eco Booster leaking oil on manifold.

While any driving conditions or speeds for no reason at all abs, traction, emergency brake system warning lamps come on. My brakes are good. Took truck to a shop and had brakes inspected and nothing is wrong with the brake system. When turn off vehicle and restart warning lamps turn off. Sometimes the check electronic differential warning lamps comes on with the 3 brake warning lamps.

OBDII code C116A, with ABS dash light on. ABS HCU needs replacing at 53000 miles. Many failures of this unit reported. Part costs $2900. Entire job quoted at $3900.

Vehicle lost brake pressure warning lights illuminated and got message saying brake fluid is low. Was able to get stopped with minimal brake pressure and found master cylinder empty. Completely filled it made it a few miles down road and it happened again no visible leaks anywhere appears to be losing fluid internally.

The contact owns a 2014 Ford F-150. The contact stated while driving 5 MPH and depressing the brake pedal, the brake pedal went to the floorboard but failed to stop the vehicle. The contact stated that the check brake warning light was illuminated. The contact stated that he used the parking brake to stop the vehicle. The contact stated that he had experienced the failure approximately 10 times while driving as well as while reversing. The contact took the vehicle to an independent mechanic and was informed that the brake booster pump and brake lines, and ABS speed sensor needed to be replaced. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was approximately 165,000.

Vehicle failed annual State (VA) safety inspection on 7/13/2023 due to Power Brake Booster issue. I see there is a recall out (NSTA#20V332) on Ford F150 for this issue but not on my VIN. Brakes are mushy and stopping time is increased.

RE: Safety Recall 16S24 Why is my 2014 F-150 not covered under Ford's safety recall (16S24) of a defective brake master cylinder? 16S24 covers defective master cylinders for the 3.5L V-6 Ecoboost engine, but not the 3.7L V-6 engine. Upon further research, it appears that both the aforementioned engines use the same master cylinder. See Motorcraft part no. BRMC203 (Brake Master Cylinder). According to Ford, the master cylinders' rear seal fails, thus leaking brake fluid into the attached brake power booster which causes pedal fatigue and possible loss of front brakes. My F-150 has a 3.7L V-6 engine, which is not covered under the recall. However, my F-150 is exhibiting the same master cylinder failure as is referenced in 16S24. My master cylinder has leaked into the power booster and the vacuum line attached the power booster has siphoned all brake fluid into the engine (approximately 60 ounces). The engine...

I was going to get some lunch and I noticed a low brake fluid message was on. So I popped the hood to check fluid level and sure enough it was. I went to auto zone purchased some fluid and filled the reservoir and all seemed fine, but before I could get back to the office the message low brake fluid appeared again. Again I filled the reservoir with fluid at the end of my shift,the message went away and I headed home. As preceded home the message appeared again and I had to purchase more fluid and repeatedly filled the reservoir to make it home . After I got home I looked around the vehicle for leaks and there was none. I explained what happened to my mechanic and he told me my master cylinder was bad and that all the extra fluid I had put into the reservoir...

Ford defrauded the U.S. Government by knowingly installing defectively-engineered parts in my truck as part of a recall and then claiming the issue was repaired. Ford obviously had so many catastrophic brake system failures it necessitated a federal recall. However, Ford admitted they never redesigned the faulty parts to mitigate the problem from happening again. This it tantamount to providing a liver transplant patient with a liver from a chronic alcoholic. Ford absolutely knew the affected parts were defectively-designed and/or defectively manufactured, yet chose to put those exact same parts back in the truck and then lie to the federal government that said parts fixed the problem. All Ford achieved was kicking the can down the road. Not surprisingly, my brake system catastrophically failed AGAIN after Ford "fixed it" during the recall. I guarantee there are other owners out there who have experienced the same problem. Ford MUST be investigated...

I only used my VIN to get this far. The issue that I have concerns a very important safety feature that I have yet to see on any vehicle. With more and more vehicles being produced with automatic braking systems, I am wondering why the automakers don't have a specific light option on the rear of the vehicle that illuminates when the ABS is activated. There are still millions of vehicles on the road that don't have ABS. This feature would inform following drivers the difference between slowing down and quickly stopping. It could be placed in the middle of the rear brake light that is in the upper middle of the rear window. So, you are probably wondering why I am bringing this to your attention. That is because I have wasted 30k of my own money on 2 different marketing firms trying to get my patent noticed, with...

Vehicle was repaired under recall Ford Safety Recall 16S24, due to failing brake master cylinder which was leading to total brake failure. The subject vehicle (VIN 1FTFW1CT6EFB00788) was taken into a Ford Service center to perform the recall repairs in Mar 2017. Ford replaced the mater cylinder at the time under the recall. Recently (10/13/2022) the vehicle experienced complete brake failure while driving with all the same symptoms described in the original Ford Safety Recall 16S24. Audible chime with full screen screen message on the dash cluster warning of brake issues. The vehicle coasted to a stop after taking appropriate actions (downshift and e-brake) to come to a stop without crashing or injuries. The vehicle was towed to a Ford Service center for diagnoses. Ford diagnoses was rear seal failure of the master cylinder which allowed all the brake fluid from the reservoir to leak into the brake booster, leading...

Hello - My 2014 F150 experiencing this issue, but FORD says my VIN is not on the recall list. Truck pulled brake fluid into the engine from faulty brake booster / master, lost all brakes, lots of smoke, brake fluid reservoir empty. Brake Master Cylinder May Leak into Booster NHTSA Campaign Number: 20V332 A loss of brake fluid may result in a change in brake pedal travel and feel, increased pedal effort and reduced front brake function, possibly requiring greater effort and distance to stop the vehicle. These conditions can increase the risk of a crash.

Catastrophic brake failure. Recal 16S24 was completed on this truck, but the "repair" failed. Either the same defective parts were put back in or new but still defectively-designed parts were installed. Current symptoms are identical to the text in the recall. Pedal goes to the floor, large quantities of brake fluid are pumped out of the master cylinder reservoir, little to no observable leaking of brake fluid is observed, so per the recall fluid is being pumped into the vacuum booster. Ford refuses to address the problem. Their official policy is no recall will be repaired more than once even if the supposed "repair" also catastrophically fails. Their goal appears to be to make the "repair" last just barely longer than 1 year so they can deny coverage thereafter and make the customer deal with the repeated failure. Failure was instantaneous in that the truck was just sitting in the...

The master cylinder failed when brake pedal was pressed. A complete total brake failure happened and i had no braking power but the parking brake, Had i entered into the main traffic and applied my brakes nothing would happen and i probably would have had an accident. I didn't have time to look for any warning lites as i was focused on beong able to stop the truck.As for my safety and others it could have been bad if not me being able to stop the truck.

Brakes went out in a school zone. Brake went straight to the floor. Could have killed a kid. I do have a 2014 model so it’s odd mine wasn’t part of the recall

The brakes stopped working and I hit my office trailer this morning and almost one of the workers on the jobsite. I didn't do any damage to the trailer or the body of my truck due to the low speed I was traveling. I have been working on cars my whole life and although I am not a certified auto mechanic I am 100% positive that the fluid from the master cylinder has leaked into the booster. Before I arrived to my jobsite the Brake light came on due to the brake fluid reservoir being empty. There is already a recall for this very dangerous failure and it should be fords responsibility to make my truck safe just like others with the Same Exact Make, Models, Years and issues.

I was driving in town. Suddenly the "check brake fluid" light came on and brakes stopped working. Had to push all the way to the floor to get truck stopped. Went immediately to an independent service center nearby to have brakes checked. Mechanic knew immediately what the problem was and showed me where the brake fluid was going into the brake booster. He also stated he has seen the problem before and there is a recall out by Ford. I immediately contacted the Ford Dealership where I purchased the vehicle new. They told me I could bring it in for repairs but checked the VIN number and said there was no recall out for my truck yet. It was not safe to drive the truck in the condition it was in. I made a very cautious and slow drive approximately 20 miles to get the truck from my home to...

Brake warning light came on and brake pedal went further down toward floorboard. Drove cautiously to auto parts store for brake fluid. Thankfully I wasn’t driving at higher speeds on a major highway. Filled empty reservoir and made it to independent auto repair shop about 3 miles away. Reservoir empty again. Mechanic says brake master cylinder is leaking brake fluid into the brake booster. Informed me of safety recall 16S24, but my VIN was not included. Same make, model, engine size and manufacturing plant as recall. Called local Ford dealership and they would not fix for free, because VIN not included. Repair cost me $1395.54! I do not understand why my truck is not covered under the recall and request a further investigation as to why Ford is not responsible for the reimbursement of the failed safety components.

Brake fluid leaking from reservoir into brake chamber required to pump brakes to stop truck

Brakes failed suddenly. Thankfully in a parking lot but 10 minutes earlier I was going 65 down the highway. Had it towed to mechanic. Brake master cylinder failure. Requires $1200 repair to replace brake master cylinder and brake booster. No open recalls shown. Very unsafe.

Brakes started grinding and a fluid like substance was coming out. Took it in for a check and brake pad had came off and caliper had busted and was leaking brake fluid.
