Ford F-150 (2009-2014) :: Vacuum Brake Pump Assembly Failed
Jun 8, 2013
2011 F150 SCREW FX4 6.5' box Ecoboost... All of a sudden I had no power assist for the brakes.
In a "unit down" situation waiting for a replacement vacuum brake pump assembly from Ford? My truck has been stuck at the dealership for going on three weeks now waiting for this part. No one seems to be able to say when the part will be available, which suggests to me that Ford is waiting on the supplier to produce more.
They're paying for a rental, but the 2013 Escape isn't anything near my F-150. A week maybe, I could understand, but on 6/11/2013 it's going to be three full weeks since my truck was towed into the dealership. How many of these things are on the road? How do they not have this part readily available?

Just wanted to report another F150 with the blown master cylinder problem and had a few questions regarding the issue. Its a 2014 Screw EcoBoost with about 12500 miles located in Michigan.
I was driving last Friday (6/19) when the low brake fluid dash lamp illuminated. I made it to my final destination, when I began to back into a parking spot the brake pedal dropped to a position about an inch off the floor. Parked the truck and popped the hood to find almost all of the fluid gone. Only having fluid in the rear axle reservoir of the brake circuit. Pulled the vacuum sensor and the booster is filled with fluid..
Called Ford, had it towed to the dealer and its been sitting there ever since.... They have no loaners and have not even looked at it yet. I'm going to assume no parts are in stock just like all of the other threads I have read on here about this issue.
A few questions I have for those of you who have had this problem or have knowledge about it.
1. How long did it take for your truck to be repaired?
2. When the master cylinder seal leaks all of the fluid into the booster and the booster is pulling engine vacuum; does this mean that brake fluid is then pulled into the crankcase of the engine?
Really looking to get my truck back soon cause I love driving it! But the '74 F250 will have to do for now ....

Haven't found any other useful info on this, but local dealer says that's where my truck is leaking oil from, and since it's considered brakes not powertrain the repair won't be covered under warranty ...
Backstory goes : dropped my truck off at local dealer Thursday to repair an oil leak from near front main seal area of the engine discovered while inspecting to initiate a bumper-to-bumper warranty through Ford ESP- their platinum warranty. I figured with all the electronic widgets and non-powertrain stuffs on this beast I wouldn't mind paying for 3yrs/36k miles of trouble-free motoring, y'know?
Apparently it's the O-ring on the brake vacuum pump that's allowing engine oil to leak. I can't even find this thing, just looking for some further explanation. I'm keeping an open mind so far, I don't suspect the dealer's just trying to get one over on me, just trying to be good and educated before I go plunk down for the repair.

2009 f150 4x4. My front hubs are ratcheting, I probably have a vacuum leak somewhere. Any trick to find it? I had to drive about 90 kilometers to get home, hope I didn't ruin anything. I don't have a vacuum pump, but I have a vacuum gauge.

Having issues with the vacuum falling off to the hubs when driving and light throttle. I know makes no sense,but kept fighting this thing making vary harsh rubbing sound since I bought it used and I know its the little collar on the back side of hub that engages to hub to make the 4x4 connection but it looses vacuum when driving and very light throttle/load.
I verified using a vacuum gauge ran inside vehicle when driving. Checked all lines and hubs,everything good. Solenoid has vacuum when running but seems to quit when light load or throttle and as soon as vacuum falls off then the collar starts to engage and rubs but doesn't fully engage. I don't get it. Unless there's something on the computer side of it shutting off the solenoid or something.

I have a 2010 F-150 FX4 SC 4x4 5.4l w/ automatic that has 52,000 miles on the clock give or take, unmodified with the only exception of a remote oil filter relocation unit.
I bought the truck with 48,000 on it and did not have this noise, I've had it back to the dealer and their best mechanic went for a ride with me and the noise was duplicated and the mechanic had the deer in the headlight look on his face and said he'd never heard anything like that before. I've searched the net for anything similar like this but have not found anything. The noise rears it's ugly head after the truck is warmed up and it first started around 55mph and went away at 65mph , then re-emerged at 75mph and left again at 82mph.
Tried the usual test things while noise was present first loading and unloading the steering left and right, (wheel bearing) no change. Next I applied the brakes (caliper rubbing) no change. Then I tried shifting to neutral (transmission or carrier bearing) no change. I also tried shifting into and out of 4x4 (transfer case) no change. If I speed up above those speeds or slow down below them, the noise disappears.
Recently... the noise seems to be more consistent and when it's present at 80mph and you let off the throttle, the noise is present all the way down to 55mph then magically goes away. The noise to me sounds like a vacuum leak in a rubber hose or a dry spinning shaft in a bushing, sort of a low hum that sounds like it's coming anywhere from the motor to the transmission area.

Plugged in my SCT when I got home, P1450 code. "Unable to bleed up fuel tank vacuum" I did a search here but nothing in the 09-up section.

I'm still googling but it seems I need to start by cleaning out the lines and evap which I'm not sure where its located. I'm going to get on a creeper tomorrow morning and have a peek but just wanted to see if any of my brothers ( or sisters ) here have had this issue. I just turned 35K miles.

2010, 5.4L... Noticed a small oil spot under the truck this morning. Took it into the shop after work, we lifted it up, and ran it for 15 min to see where the leak was coming from, and the truck did not leak a drop... until we turned it off. The oil would slowly leak near the power steering pump pulley. But only when the engine was not running ...

I have a 2013 f150 & the fuel pump relay fuse burnt out. I unhooked the battery cable "wasn't thinking" & took the fuse out & replaced it. Now my truck wont get over 3000 rpms & is driving like i got bad fuel or something. & now its throwing codes about my trac & I don't know why. Just from unhooking the battery cable & hooking it back up. What it is??

I replaced a water pump on a customers 2013 5.0L truck this week. The bearing was totally shot and lost all the coolant. Truck only had 46000 miles on it, is this common?

I have an 2002 Volkswagen GTi 337 edition with the 1.8t engine in it. My check engine light came on so I went to my local autozone to check the code and that's what code it threw on the ODBII sensor. It says my problem could be a "failed clutch vacuum vent valve switch". It also revs about 100-200 rpms extra in between shifts and I'm not a mechanic but know a little about cars. I just don't know if I should replace the OEM clutch safety switch or what I should do about this.

The fuel gauge sender quit the other day so Im replacing the pump assembly. I believe in replacing fuel and ignition related parts with factory equipment. So I was going to get a Ford Motorcraft pump, but my wife checked for one through her work(local parts store). The counter guy found one that said original equipment, called them and was told "It is the same pump that gets installed on the assembly line". Well it came in today and its a Delphi. I was expecting a Ford pump. I associate Delphi with GM and I know GM pumps go out all the time. I know Ford pumps go out too, but I know several people with GMs that have replaced pumps multiple times within 100000 miles. Is Delphi worth taking a chance on?

I put on new Power Stop drilled and slotted rotors with Hawk ceramic pads. I did the brake in runs and could feel the stopping power improving. When I got back to the house I looked at the rotors and I noticed that on the driver's side the pads are not parallel to the rotor. They are hitting on the outer edge of the outboard side and the inner edge (closest to the hub) on the inboard side. Took it all back apart and I can't see and reason for this. Double checked all the mating surfaces and didn't see any problems. I torqued the caliper brackets to 150 ftlbs and the lug nuts also to 150 ftlbs. Is it a problem the caliper sliders?

Have an issue with their third brake light leaking. The shop priced 275ish to replace/fix leak. I figured a 5 dollar tube of clear OSI would do stop the leak just as well. Any reason why I shouldn't just seal the brake light instead of replace.

I washed my truck for the first time tonight, and while doing so, I noticed what looks like water got into the third brake light on top of the cab. Is that a common issue and is there an easy fix? I've seen foam inside at the very bottom of the light fixture, it kind of looks like there are two housings though, with the foam in between. I checked the inside headliner, and everything there is dry.

I see several threads regarding engines that wont start for no apparent reason. My reason was a failed fuel pump relay. This sucker is hidden in the dash below and to the left of the radio. I got to it by taking out the ash tray. There are three relays under the cover. The upper left is the fuel pump relay. The one to the right is the turn signal relay. I don't know what the bottom left is for.

I have a '09 Ford F-150 Lariat, 5.4 with a lighting difficulty. Previous had it in for service for exterior lighting that was intermittent and uncontrolled. A door module was replaced and reprogramming performed by the dealer. Worked OK for awhile, but today I noticed that brake lights were on while the truck was parked.
Checked all that I could think of then pressed the caution light button, activating the front/rear caution lights. Turned the caution button off. Brake lights went off. About an hour later, noticed the brake lights were on again. Tried different things to deactivate the brake lights, but to no avail - brake lights stayed on. Have disconnected the battery - this is where it sits at the moment.
