Service Brakes Problems of Ford F-150 - part 1

Issues with my 2025 f150 tremor when I applied my brakes firmly, really not that hard ( not hard enough to skid) my truck locked into park and I wasn’t even able to put it back into a gear with a flashing message! couldn’t get it back into gear for about 30 sec to 60 sec until a message stopped flashing. Had this happened in traffic or on a freeway this could have been really bad especially in traffic. Very dangerous!.

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.

The driver's side rear light is full of moisture and some water. It is available for inspection. The Ford dealership in beeville texas coastal bend Ford inspected it already and informed me that it would cost $1,400 to replace and that it was only going to get worse. They also informed me that Ford allows a certain percentage of moisture and water to be in there safely. When you see the pictures this is definitely unacceptable and unsafe. This is causing the reverse lights to flicker intermittent. The moisture accumulation inside the lights can result in inoperative or flickering reverse lamp function. Inoperative reverse lamps may reduce the awareness of other motorists or road users of the driver's intention to operate the vehicle in reverse gear increasing the risk of injury or crash. I bought the vehicle from a Ford dealership in austin texas less than 10 days ago. I reported it to them and they stated it wouldn't be covered under warranty. The best assessment in my opinion of cause is going to be microcracks in the outer lens. Because my truck is a 2023 Ford F-150 king ranch, and there is a known recall for the same issue for 2022-2023 lariat and platinum models, so this can't be a coincidence. Refer NHTSA recall number 23v-418.

There is also a pending master cylinder recall that Ford said the didn’t have parts for and still haven’t heard back from them on that. Please investigate this dangerous situation.

My 2021 Ford F-150 intermittently displays the warning message “reverse brake assist not available – see manual” when the vehicle is placed in reverse. When this message appears, the reverse brake assist / parking collision warning feature is not available, which may reduce safety while backing up. The vehicle was inspected by a Ford dealership. The dealership confirmed dtc u3000:49 in the ipma module and identified Ford TSB 23-2040 as applicable to the concern. The dealer stated that the repair requires an ipma software/module update and calibration. The quoted repair cost was approximately $1,100. This appears to be a software/programming-related condition affecting a driver assistance and brake-related safety feature, not normal wear and tear or a failed mechanical component. The warning is intermittent, but it has appeared multiple times. The vehicle is available for inspection upon request. No crash, injury, or fire has occurred. Ford customer support was contacted and case number xxx was opened. Ford advised that no active warranty, recall, or customer satisfaction program currently provides repair cost coverage, and that because this involves reverse brake assist, I may choose to file a safety concern report with NHTSA.

My 2017 Ford F-150 is subject to safety recall 25v236 / 25s37 for a faulty brake master cylinder that can leak fluid and cause a loss of front braking function. I contacted the dealership to have the safety repair completed, but I was informed that the necessary replacement parts are on indefinite backorder with no estimated arrival date. No interim safety defect remedy or loaner vehicle has been provided by the manufacturer. I am forced to drive a vehicle with a known, critical braking defect, posing an immediate safety risk to myself and others on the road. The manufacturer has failed to remedy this safety recall in a timely manner.

The contact owns a 2018 Ford F-150. The contact stated that while driving 65 mph and hauling a trailer, the brake pedal was depressed and went to the floorboard. The vehicle failed to stop immediately. The contact drove the vehicle into a ditch to stop it. The message "low brake fluid" was displayed, and the brake warning light was illuminated. The front driver's side tire was damaged from the ditch. The air bags did not deploy. There were no injuries sustained, and no police report was filed. The vehicle was towed to the residence.

In November of 2025. I took my truck, 2017 F-150 3. 5 liter engine, to crest Ford in flat rock mi. There was a recall on the master cylinder (25s37). On 5-26-2026 we were following a friend to take his car to dean arbour Ford in east tawas for service. While trying to slow down for a turn my brake pedal went very soft almost to the floor. I was able to slow my truck down enough to make the turn. I then proceeded very carefully to the dealer. It was all country roads with no traffic. By the time I got to the dealer my brake pedal went all the to the floor. I almost had to use the emergency brake to stop. If this would of happened on the expressway we could of been killed or killed someone else. There was no way I could of stopped in an emergency. Upon investigation the new master brake cylinder that was put on in November of 2025 failed. I was told they don't know how long it will be to get a new part because Ford requested all the new master cylinders to be returned. So it sounds to me that there could be alot more vehicles with bad master cylinders that customer had replaced and do not know they are bad. I was having no issues with my brakes on the old master cylinder. I am also being told that it's a warranty issue because the recall on it was closed when the master cylinder was replaced in November of 2025.

While driving this vehicle, the brake line was cut after making contact with the a arm assembly, at the highest point on the line. I immediately lost my brakes as the brake pedal went to the floor. I am extremely lucky that I was able to stop within the parking lot that I had just entered and did not have to make an immediate stop.

Tried to turn on vehicle one morning and it would not start due a parking brake error message & a warning light on the dashboard. The message on the screen behind the steering wheel stated “park brake fault service now” and there was a clicking noise heard coming from underneath the truck. I tried to reset the parking brake by pressing and holding the button as indicated online but it didn’t work. The brake also physically revolted at me pressing down on it and would stutter/thump and not let me press it down fully without heavy resistance. The clicking noise continued randomly even when I was not in the vehicle. Then the door locks stopped working with my car keys, I could only open the drive door manually. I had no means to jumpstart my battery. I called Ford local dealership to come check the issue incase it was a recall issue that had not been reported for my vehicle yet. They are scheduled to come Monday 6/1/26.

- master cylinder leaking into booster pump. ~lost brakes going 65mph, had to drive into a grass area to slow down. No warning lights until I lost all brakes. - transmission hard shifting and unreliable gear selection ~ this truck has missed gears when passing intersections and has almost caused a wreck multiple time.

I was driving by and received multiple warnings about brakes. Brake assist, one pedal driving, reverse brake assist, general brake warning. After the came on the brake were spongy with a hard brake after applying more pressure to the pedal. I needed to apply more pressure because the car was not stopping. I almost hit various cars on the way home because there is certainly an adjustment needed to my braking habits. Very dangerous and unsafe. I took the truck to the dealership and quoted me around $2,500. This is something I have no control over and see that there is a recall on this issue for a 2025 model, but my vehicle does not fall under this recall.

The epb system has a fault and service now code. This puts a risk on safety of me, passengers and others on the road. This make and model is a single exhaust unit and I believe it has to do with an open recall. July 21, 2023 NHTSA campaign number: 23v509000 unexpected activation of electric parking brake unexpected activation of the electric parking brake while driving increases the risk of a crash. Nhtsa id number: 23v509000 manufacturer Ford motor company components parking brake potential number of units affected: 870701 summary Ford motor company (Ford) is recalling certain 2021-2023 F-150 vehicles equipped with a single exhaust system.

I was on the highway doing 70mph and went to break and I had no brakes. I was terrified. I kept trying and I got it to break and pressed again and lost them again. Eventually the pressure on the breaks returned. The remaining ride home was just scarey.

Brakes completely failed. Foot went to the floorboard and car did not stop. Drove until is was slowed down enough to throw it into park. Engine light stated low on brake fluid. Filled it up and it went about a mile before brakes failed again. Took to a mechanic who determined that brake cylinder and booster had failed. Called Ford who said my 2018 Ford F-150, built in kansas city was not in the Ford April 14, 2025 recall (25s37) as the build date on my vehicle was a few months after the may 19, 2017 cut off. However it is clear that later built models also had the same problem with the defective brake cylinder as the earlier builds. I suspect they used the same part. Ford should expand the date of brake failure to cover repair of later models with failed brake booster and master cylinder.

About 30 mins prior to the incident,the accelaration was vey slow getting upto only 30/35mph message appeared in dash board instructing to schedule maitanance service soon. My last service was done only 2 months ago. Anyhow I decided to drive the nearest Ford dealer. On exiting the freeway,the ramp was downhill and the braking system completely failed and I crashed into the pavement. All the airbags came on. I have sternal contusion.

On two occasions I've attempted to have this recall work done at a Ford dealership. Today after holding the vehicle for the entire day, the service department at koons Ford in falls church returned the vehicle without performing the recall replacement. Further, they did not notify me the work was not done leaving it to me to call to inquire as to whether the work was done. This is the second attempt at having this recall work performed at Ford dealerships. In both cases, the recall work was not performed.

When I'm driving my truck, usually when I have come to a stop on an incline, the parking/emergency brake will engage on its own. For example, most recently I was pulling out of a driveway with an incline. I was stopped at the bottom of the driveway to wait for the roadway to clear before I pulled out. When I hit the gas to go, the rear wheels skidded and the truck came to a stop in the oncoming traffic lane. I looked at the dashboard and saw that the parking brake symbol was on, indicating that the parking brake had engaged. I did not engage the parking brake- the truck did it on it's own.

1)brakes were changed, rotors and pads. Brakes were bled 3 times and it still does not stop correctly. Even when the brakaes are on, it releases itself. 2)truck keeps shuddering and loosing power. 3electronics will not stay bluetoothed and it connects and disconnects all by itself all the time. Appears there are recalls on these 3 issues.

I was driving and my brakes gave out a bit and my brake pedal was hard to press down and when I pressed down there was a grinding sound. Also a red warning message said check braking system. Has been confirmed for 3. 5l ecoboost engines, which is what I have.

The brakes aren’t working properly due to loss of vacuum. This happens anytime I’m stopping at a red light or parking which can result in me hitting someone or another vehicle. This has been confirmed by firestone compete auto care but they were unable to fix it. Ford says this TSB applies to the same year but not to the plant this car was manufactured. There were no warning messages.

There was an audible chime coming from the vehicle. The brake fluid reservoir was very low. The vehicle was taken to an independent mechanic, and the contact was informed that the brake fluid reservoir was empty, and there was no indication of a leak.

The brake light came on right as I parked with the warning that my brake fluid was low. Opened the hood and noticed the reservoir was low but could not see any sign of a leak. When I pushed the brake to put the truck in reverse, the pedal went to the floor. After testing it in the parking lot, the truck eventually stopped after having pressing the pedal all the way down. I was able to get it to the auto shop down the street. That is where they told me there was a recall out for the master cylinder leaking internally (recall 25v-236) but my VIN is not part of it. Took it then to the Ford dealership where they confirmed I needed a new master cylinder and booster but it was not covered under the recall.

It was Tuesday 04/14 I had just left a store. Drove to the corner stop sign and applied the breaks which have always been just fine, easy to stop and slow. Until thst day I eased on the breaks and all of a sudden the peddle went to the floor. I came home and called my mechanic shop. They told me to bring it in. When I did they told me the master cylinder had gone out and was leaking all into the booster. They felt it was unsafe for me to drive it. They gave me a loaner vehicle. Upon returning to my home that's when I saw all the break fluid running down my driveway where I had parked when I got home from the store the day prior. Which I hadn't noticed before. So, now I'm without my vehicle because I simply can't afford a $900 repair bill. I've looked it up and on your website it shows in 2025 there was a recall on the 2014 Ford F-150 that named the master cylinder as a problem. It also stated that on google. Please help.

Attempted to have my local Ford dealership, sam galloway Ford, ft. Myers, schedule the recall on 4/14. Was told they parts are on a back order. Contacted Ford corp. Via chat with ai, then an agent asking in the brake master cylinder replacement parts were on a national backorder. I was told no and they requested the name of the dealership. Pressed the dealership for an appointment. This was granted 4/23, 7:30am est. Arrived and was checked in. At 10am was told they do not have the parts. A supervisor explained that on Monday they had to return 32 parts packages to Ford because these were defective. Contacted Ford again, they denied that the replacement parts are defective. Who is one to believe at this point?.

On 16 f150 brake controller not functioning. 2020 2022 recall. In FL. And it’s costing me $600 to repair! why is mine not under recall?.

Multiple front brake line ruptures on 2016 f150 putting safety at risk. 7/26/2023 front passenger side brake line rupture while driving requiring new brake line. 4/6/2026 front driver side brake line rupture while driving requiring new brake line, replaced front passenger side brake line again because it was cracked and about to rupture again. Ford is using defective brake lines, brake lines should not be considered a routine maintenance item like a car battery. This is putting my family at risk and other drivers.
