Ford F-150 (2004-2008) :: Brakes Locking Up - Fix?
Mar 10, 2016
my front brakes have been locking up here recently. I think it my be due to a blockage in the resovior. I had taken it apart upon the first spell of it locking up, had my buddy press the brake pedal a few times with the lines from the res disconnected and it seemed to be be a little clogged at first and then freed up once it was stepped on hard a few times. So i reassembled the system and bled the brakes out and it seemed to be fine for about 70 miles or so. Then out of no where it started locking up once again.

2008 F-350 wheel will lock for no reason. I think the Hydroboost has a hair line crack it and when the temp and pressure reach a certain number then it sends brake fluid threw the crack to the caliper? I also heard it could be in the ABS because its locking just one wheel?

I have a 2004 Ranger 4x4, 4.0, auto and have trouble with the back brakes howling, locking up and generally driving me nuts. I've replaced the drums, shoes, cylinders, emergency brake cables and all the hardware. We've bled all 4 numerous times, blown out the lines, looked for leaks and done all we can think of. What am I missing?

I have a 2005 F250 & both front calipers are locking up. I have replaced the front pads, no change, my mechanic installed a new master cylinder. No lockup for about two weeks until today. Front calibers are locking up again.

I have a 1999 f250 super duty, that was wrecked a few months ago. I have put the truck back together with the mechanic. The front drivers side was wrecked. The power steering fluid tank was cracked and had to be replaced. Also had problems with a box behind the drivers headlight? I did hard wire it together and it fixed the problems i was having the the speedometer and the transmission not shifting correctly.
Everything is put back together now but I drove it today and the brakes locked down after driving it a few miles? Had to push the truck hard to get it back to my house, a mile or so. If i let off the gas it would come to a quick stop. It is ALL four brakes locking up. If it sits for awhile they unlock but will lock up again after driving. The truck is lifted and the ABS light has come on.
It was not on before but i am pretty sure the ABS is disabled on the truck. the wires are hanging down by each tire. This is how they truck was when i bought it. Not sure what is causing the brakes to lock up.

In removing the COPs on my 2004 F150 Lariat 5.4L for a spark plug change, I noticed that the locking tab on one of the electrical connectors that plugs into the COP is broken. The previous owner had a zip tie on it to keep it on. Can I purchase a new connector and splice it on so that I don't have to use a zip tie? If so, what is the part number?

When I put truck in 4wd rear end starts locking up. Take out of 4wd its fine. Just put 2 quarts of fluid. They didn't have the 75-140 so I put in 85-140 was that bad. Had rear rebuilt a year ago. Mechanic said he had to put a different gear assembly because ford didn't make the original any more. Ever since this was done rear just never seemed right. Now in 4wd if I go straight it's fine but as soon as I make a turn rear locks up almost coming to a grinding stop.

this is my brothers truck 05 f-150 4x4, i put brakes front and back and flushed the system about six months ago now. the other day when he was coming home from college the front passenger tire locked up. he drove it home and i went over took it apart nothing was sticking put it back together and it was fine. now today he call it stuck again so i just pulled it apart, pads are now purple from the heat, pins are free, caliper moves i put a small piece of wood in it and had him press the brakes the caliper moved out and i pused it back in, reinstalled everything and its not stuck no more. what do you think is causing this? my uncle says it could be the abs box acting up, when he bought the truck my dad made him buy the extended warrenty but he wont pay the 100 dollar deductible because this past winter we all went out in the two foot of snow and he got stuck so i pulled him out and our dad says thats what f$ucked his brakes up so now his is pissed. so how can i fix this for him? oh it only has 42k on it

Ok, So, Im 40 miles from home stuck in ice and snow in a hotel.. (my wife works close by- thought it would be safer than driving in the 10 inches of snow we got 3 days in a row) so, I go to pick her up tonight and I engage 4hi.. I hear the click and the light comes on.. but no clunk of the hubs locking.. I drop it in 4 lo.. it shifts in low.. but the hubs are not locking..
I hear a ticking sound as I drive and when I put it in 2wd it goes away. I turn off the truck, turn the wheel hard both ways .. get out and I can physically turn the drive shaft and I hear the ticking in the hubs. If I read correctly when the truck is off these should be locked?
is it possible the vacuum is not releasing? I also get the groaning when I start up of the air diverter.. that im told is operated by vacuum.. so I am guessing I have a vacuum problem??

My driver door on my 06 F150 crew cab stopped locking/unlocking recently. I purchased a new actuator and installed and it worked great. About a week later it stopped working again. But then in order to unlock the door from outside you had to turn key and pull on handle while the key was still turned. I was about to break open door again when it made a strange electronic type sound when I was leaving for work (when auto lock activated). After that it started working again - for 3-4 days. Now it stopped working again. I can open door fine from inside but lock won't stay unlocked. As soon as I release handle it locks again.

I just bought a 2007 fx 4 with 116000 miles it has the triton 5.4. I know I test drove it good etc well I am out of town with work right now and drive it on a 400 mile trip and noticed that when you are in overdrive and going up a small incline it acts like the truck is locking up, if i get on the gas a lil and make it shift it stops.
The truck shifts smooth and everything on this truck is tight no clunks or nothing. Ihope its not the transmission and sometimes after putting it in park and idling and turnings steering wheel it will start idling really rough . What could this be only does it speeds 50-57 like i said if i make it shift it stops....

My 2008 is 4 years old now but only has 27k miles. (I'm retired.) However I am really disgusted that it has had so many serious problems. Most recently, the trunk will not open all the way. I noticed this before it went out of warranty but I assumed it just needed some WD-40. In fact I remember another poster on this forum actually making fun of another owner who complained about the trunk not opening all the way. Well, now the dealer tells me I need a whole new trunk support system for $388! I'll just live with it as long as I can stand it.
Additionally, the doors often don't lock when I push the thumb lock on the outside of the door. I've tried both doors and the trunk. Of course the dealer couldn't find anything wrong. I know I could try the key fob but I keep it zipped up inside a pocket inside my pocketbook and never fool with it - a feature I do love about the Prius. Having problem with the trunk not opening all the way?

We have a 2008 Lexus RX350. We prefer the horn over beep to notify us the doors are locked. Can we change this or does the dealer have to do it?

I'm having a problem with my rear drum brakes locking up when I press the brake pedal. I've had this problem before, but ignored it because it wasn't too bad. It would just release after taking my foot off the brake pedal.
1998 F-150 XLT supercab 4x4 front discs, rear drums 4.6L v8 175k miles
I cleaned my master cylinder and bled all brake lines so they have fresh fluid. Now that my brakes work way better, my rears just lock up. I put new brake cylinders on, still locking up. I went to a junkyard today and replaced the proportional check valve, brakes still locking up.
Could I maybe have did something wrong when cleaning the master cylinder? I'm sure I put it back together correctly. Anything else i should look at? bad lines maybe?

I have been having hub locking trouble and finally located a bad vacuum hose. Hose has been replaced. Now when I engage the 4WD and apply a little power, I get a terrible bang out of the front end, then the truck moves on. Sometimes there is a second bang, sometimes not. The chain appears tight in the transfer case and the ujoints look ok. I have turned the wheels with hubs locked one at a time and the joints are free.

2004 F150 XLT, 5.4, 69,000miles.
I took my truck into Brake Check because my brakes were squeaking and the rotor needed to be worked on, when I slowed down the truck would slow down smoothly....it felt like I was pressing hard then releasing etc. I knew it needed new pads etc.
Well, they replaced the Pads, and did Rotor Reface on all 4. They recommended getting the Calipers Maintenance (front 2 wheels). They wanted $800 for new rotors too (in addition). I told them no.
Fast forward around 6 months. Truck was braking great, no squeaks etc for about 4 months. Then I begin noticing huge amounts of brake dust on my wheels. Might be normal not sure.
2 months later, but truck now squeaks again while braking. And when I'm going slow, I like in a parking garage I can hear this clicking noise while I'm on the brake. CLICK.....CLICK.....CLICK....CLICK.
If you coudn't tell, I don't know much about my truck. I'm trying to learn.
Well, whenever I slow down from ~50mph, my truck vibrates like nothing I've ever seen before. My windshield wipers are bouncing around it's so bad.
I took it to a Ford Dealership to get the works done, where they rotate the tires and change the oil etc, and inspect the brakes. The guy said the rotors need to be machined.
That's not normal right? I don't drive a lot. I don't ride the brakes, I haven't had to brake hard. 6 months from the work I've had done from Brake Check, and the rotors are bad again?
I'm just going to pay Ford to fix this issue and not go back to brake check because that means I'd have to drive 3hrs. I'm curious though, shouldn't their work on the rotor still be good.....not causing them to be worked on again?! I like my truck a lot, the brakes are just pissing me off. My last truck, a 2002 ford...I had till last winter till someone rear ended my truck totaling it, I never had to do any brake work on that thing.
I got suckered into buying the extended warranty for my truck, and it says it covers the calipers.
I'm taking it into a different ford dealership that is in my town next week, and was curious if any of you had some insight on my brake situation.

After replacing the Front Rotors, calipers, and brake lines on my 2005 F150 Super Crew I have spongy brakes. I have also replaced the master cylinder. I have bled the brakes as well as a reputable repair shop has done the same. We are both at a loss as to what is wrong. The ABS light is on now after the replacement of these parts. This issue did not exist prior to changing these items. This was done to hopefully eliminate brake shudder that I have been experiencing for some time.

I just had new shoes, hardware, wheel cylinders, drums, leaf springs, rear shocks, and shackles put on. The brakes were done about 4 or 5 months ago and the springs and shocks just a few weeks ago. The rear brakes were locking up after I had the work done, but I thought they were just too tight. I loosened them a little but it only worked a little.
Now it's starting to lock up pretty much every time I apply the brakes. The ABS kicks on and the rear tires skid. I took the drums off today and didn't see any leakage or anything out of the ordinary. They weren't too tight and I readjusted them but they weren't out of adjustment much if at all. I looked at the Ford symptom chart and it says for brakes that lock up easily there could be sticking or binding components. I didn't see any. Then it says check parking brake components.
Now I see they didn't hook up the equalizer bracket that goes to the front leaf spring hanger when they changed my springs so I assume thats why my parking brake pedal goes to the floor. Then it says check the shoes and linings, which are fine. The last thing it says is to check the fluid control valve. Which I'm guessing is the prop valve.
The only way to check it according to Ford is swap it for a known working valve. One person told me that it could actually be a bad brake booster check valve. Is that possible? Anything else that's common? It's got 272,000 miles on the frame but everything's been changed that typically wears out at least once.

Driving home from work yesterday, dry roads, truck unloaded, running around 50mph, had a dog almost run out in front of me. I hit the brakes hard and came to a stop. But, I noticed that my brakes did not lock up the tires. This was a bit of a surprise. My former 2003 Cummins would easily lock them up. Is my truck an anomaly? Can lock up your tires during a hard/panic stop?

AC compressor clutch bearings went bad (went AWAY, actually) and the serp. belt snapped. New clutch went on just fine and works great, but after about 20 miles the power steering pump pulley cracked and started spinning on the shaft and the new serp belt jumped half off and ate itself.
So last night I finished putting in a new pump and pulley. Flushed out the lines with new fluid, manually bled the new pump and then followed the bleeding procedure in Haynes carefully. All looks good. Pump spins freely and runs very quiet. No noise or hesitation lock-to-lock. No leaks. Fluid level holds steady right at the half-way mark on the reservoir.
Sitting in my yard it turns smooth and very easy all the way through the whole range.
BUT, out on the street I'm getting very frequent but random lock-up where the wheel doesn't want to turn AT ALL (I'm a big guy and it's HARD to turn)! And then I'll jiggle it a bit and it's smooth as silk again. It's done it while moving fast, moving slow, and standing still. I drove about 30 miles testing it out and it seems completely random when it will lock up, but it did it about six times in half an hour. And when I got home and parked? Perfect, smooth steering.
What could be doing this? Prior to the troubles last week, steering was perfect, so I don't think the steering box is bad. (Could be, of course...).
