2014 Ford F-150 brakes problems

Filed Oct 6, 2026 · Brakes · RI · crash

During a panic stop the brakes failed and the pedal went to the floor resulting in a rear end collision. The vehicle is currently with the mechanic but he believes it a failed brake booster. When I checked for related problems it seems the same brake booster (EL3Z-2140-E) in my 2014 F150 V8 5.0L was used in the same year 3.5L but yet the recalls (16S24 and 20S31) didn't include my vehicle

The contact's mother owns a 2014 Ford F-150. The contact stated that while his wife was driving 65 MPH, the brake fluid warning light illuminated. The brake pedal was depressed and went to the floorboard. The vehicle failed to stop. The contact's wife engaged the parking brake, and the vehicle was able to slow down, and the vehicle was pulled over and parked in a parking lot. The manufacturer was made aware of the failure and informed the contact that the vehicle was previously repaired under the federal safety agency Campaign Number: 16V345000 (Service Brakes, Hydraulic), and that the warranty had expired.

On July 30, 2026, while operating my 2014 F-150 under normal driving conditions, the dash cluster information screen displayed a "Brake Fluid Level Low" warning. Moments later, the brake system experienced a sudden/catastrophic loss of front braking performance. The brake pedal became severely spongy and traveled completely to the floorboard, requiring drastically increased distance to bring the vehicle to a stop. Due to ineffective braking, I missed the driveway of the parking lot I chose to inspect/determine what the issue was and subsequently could not stop the truck within the confines of the parking space. This brake failure put me, my family as well as oncoming traffic and pedestrians in jeopardy of injury or death due to collision. A mechanical inspection of the vehicle revealed the rear cup seal inside the brake master cylinder had failed. This internal seal failure allowed hydraulic brake fluid to bypass the cylinder and leak directly into the vacuum brake booster, completely contaminating the booster assembly. Without effective braking, the truck was deemed too dangerous to drive so it was parked and unused until replacement parts could be installed. This specific component failure, internal seal degradation, and resultant fluid contamination of the booster is identical to the safety defect detailed in the federal safety agency Campaign #16V345000 (Ford Recall #16S24). However, this specific vehicle was excluded from that safety campaign solely because it is equipped with the 6.2L V8 engine, rather than the recalled 3.5L engine, this despite using the identical Hitachi master cylinder. The Ford Corporate Consumer Relations was unwilling to assist with the purchase of replacement of the master cylinder, booster but did offer to record my complaint and issue a case number for engineering review. The defective master cylinder and contaminated booster assembly have been retained for inspection if required or requested.

While driving, brakes pushed to floor, and vehicle alarm beeped showing Low brake fluid sensor had tripped. Brakes not working properly, pedal goes to floor, brake fluid added to refill and fluid emptied out of master cylinder reservior two more times, vehicle inoperable to drive with no brake pressure. Open safety recalls for Ford F150 models 2013-2014 #16S24, and for F150 Models 2014-2017 #20S31, both specifically for the 3.5LV6 Ecoboost engine, which I have, but Ford is saying that mine is not covered for the same brake master cylinder / brake booster issue.

The contact stated that the brake pedal was depressed to the floorboard, and the vehicle rolled to a complete stop. No warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a leaking brake cylinder. The contact was informed that the brake cylinder was leaking onto the brake booster. The contact was informed that the brake cylinder, the brake booster, and the brake fluid reservoir needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure but provided no assistance.

My 2014 Ford F-150 previously received Ford's brake master cylinder recall repair under the previous owner in November, 2016. On XXX, at approximately 108,372 miles, we were towing our travel trailer and had just begun a planned vacation. Within approximately five minutes of leaving home, a warning chime sounded and a "Brake Fluid Low" warning appeared on the instrument panel. I immediately exited the roadway and pulled into the nearest gas station to determine the cause. Within moments, the brake pedal traveled completely to the floor, leaving the vehicle with virtually no braking capability and making it unsafe to operate. Because the truck was towing our travel trailer, we had to disconnect the trailer in the gas station parking lot. The truck could not be driven safely and had to be towed to Kent Parsons Ford in [XXX]. My son had to bring his own truck to tow our travel trailer home because our truck was no longer capable of doing so safely. Kent Parsons Ford inspected the vehicle and documented the following diagnosis on the repair order: "Verified customer's concern. Found master cylinder seal failed and filled booster with DOT fluid." The dealership replaced the brake master cylinder, brake booster, brake fluid, and related components. The failed components may no longer be available for inspection because they were replaced during the repair. I paid $1,793.38 for the repair. The dealership's diagnosis documents the same failure mechanism described in the federal safety agency Recall 20V‑332 (Ford Safety Recall 20S31), involving failure of the master cylinder seal that allows brake fluid to leak into the brake booster, reducing braking performance. Because this vehicle had already received Ford's recall remedy in November 2016, I am submitting this complaint to document that an authorized Ford dealership identified the same failure mechanism after the recall repair had already been completed. I respectfully request that the federal safety agency investigate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

the federal safety agency / Center for Auto Safety Formal Complaint Vehicle Information: * Year / Make / Model: 2014 Ford F-150 * Component Category: Service Brakes, Hydraulic / Anti-Lock Brake System (ABS) * Affected Part: ABS Hydraulic Control Unit (HCU) / Valve Assembly (Part # DL3Z-2C215-A / DL3Z-2C215-C) Incident / Issue Summary: I am reporting a critical safety concern involving a failure of the Anti-Lock Brake System Hydraulic Control Unit (HCU) on my 2014 Ford F-150, combined with an indefinite manufacturer supply chain failure that renders the vehicle unable to be repaired to safe operating standards. The electronic ABS control module on my vehicle was inspected and rebuilt to functional specification; however, diagnostic testing confirmed that the internal mechanical/solenoid valves within the Hydraulic Control Unit (HCU) assembly are stuck/failing. This internal valve failure disables key safety features, including Anti-Lock Braking (ABS), Electronic Stability Control (AdvanceTrac), and Traction Control. Upon attempting to purchase an original equipment manufacturer (OEM) replacement HCU assembly through Ford Motor Company and authorized dealerships, I was informed that the critical safety part is on an indefinite nationwide backorder with no estimated delivery date (ETA). Safety Risk & Regulatory Impact: 1. Loss of Safety Features: Without a functional HCU assembly, the vehicle operates without active ABS or AdvanceTrac traction/stability control, significantly increasing the risk of wheel lockup, vehicle skidding, and loss of directional control during emergency stopping or adverse weather conditions. 2. Unavailability of Safe Parts: Due to high failure rates across 2009–2014 F-150 models, the replacement supply chain is completely exhausted. Independent repair facilities refuse to install unverified, used, or salvaged junkyard units due to severe liability and safety risks. 3. Indefinite Stranding / Unsafe Driving: Owners are forced to either leave their primary vehicle

The master brake cylinder and components thereof are leaking and failing, leading to decrease braking power. Yes it is available for inspection. But FORD says my truck is not covered under the recall 20S31. Having this problem puts my family in danger every time we drive this vehicle, I have 3 young children 11,8, & 6 years old. There was no warning light or message prior to the failure. When I called FORD they said it was not covered under the recall and basically it was my problem for repair.
