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?
View 1 RepliesTwo weeks ago my front left wheel would start shaking like hell when I brake, not at first but after say may eight miles of driving. I have never been in a vehicle shaking so violently and after proceeding from a stop it would continue until it cooled down. I tore out the caliper and made sure everything was clean and lubed and also to make sure I did not put the pads on wrong. Fast forward one commute and the same crap. I could not go faster than 45 mph without feeling like it was going to disintegrate.
When I got home the damn thing was smoking. I managed to get it to the dealership this afternoon and two hours later the guy told me that the guides just needed some cleaning and grease. They did not want to charge me anything (draw your own conclusion) for it. I was told they drove it up/down hills and it was alright. I left kind of suspicious and four miles later the problem revealed itself again. My next thought it maybe axle end play, bad bearings or joints? Intermittent why? 2004 f150 lariat 4x4 ....
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.

Last week I broke my front right caliper. I replaced the caliper, rotor and pads. Now, when I apply the brakes I pull to the left. I took the truck into my repair shop and let them figure it out. They were unable to repair the truck. They replace the master cylinder, all brake lines, calipers on both sides, brake pads, bearings on both wheels, vehicle alignment, tire balancing and tire rotation. The tires are three months old. Prior to last week i did not have any problems braking or steering. Driving at 60kmh the truck goes straight until i gently brake, it will slightly pull left.
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.
View 9 RepliesMy 97 f150 had been sitting for a while and after a few miles I could smell brakes and the left front rotor was hot. So I removed the caliper to see if I could free it up. When i push 1 piston in with a C clamp the other one comes out and visa-verse but I cannot push both in with 2 C clamps. When I push the brake pedal they both come out. Its like there is a check valve in the line. How should I go about trouble shooting this?
View 1 RepliesI've changed brakes on tons of front wheel drive cars, and two wheel drive trucks. But NEVER on a 4wheel drive Super Duty. My truck needs new front brakes now!!!! its a 2003 F350 4X4 -58,000 miles. I was just wondering from you all, how hard is it to change brakes on a 4x4 truck? Do I have to remove the Hub or lockouts?
View 5 RepliesFront and back brakes heating up and locking on intermittently brake pedal feels normal this has happened 3 times over the last 500 km of driving pedal not sticking down break fluid ok no swelled lines today noticed front left and rear right rotors were hotter than front right and rear left once vehicle sits they release and all is good no abs lights or any other warning lights on.
View 1 RepliesHave 2005 excursion. Just did ball joints , wheel bearings all of them, axle joints and seals.Also warn manual hubs. Have a intermittent scraping grinding noise sounds like driver but could be both front.4wd works fine in high or low, no vibration just this annoying noise. took brakes apart and no funny wear or foreign object in dust shield.
View 3 RepliesTruck is an 89 single cab, single rear wheel F350 4x4 with 7.3 non turbo diesel and a c6 trans. not lifted, stock size tires. If you hit just the right bump, regardless of speed, the front end just goes crazy.. tires and wheel shoot violently side to side and its very frightening/dangerous. you can just barely hold the wheel, front end is bouncing and whole truck shakes from such rapid camber change as the contact patch swaps from inside to outside of the tread.
Tie rod end, draglink, steering stabilizer (add on,) shock absorbers (rancho,) and a wheel bearing are all brand new. With each part replaced the shake felt worse (since more of it was transmitted to the steering wheel rather than lost in the sloppy parts) and i took it off the road immediately.
Brand new steering box, put it back on the road, did it again less than a mile away. It rained all day so i haven't jacked the truck up again and really, I am quite sick of this problem.
I have a 2008 f350, crew cab,6.4L. with 27,173 miles. may have a problem with the steering, seems to be tight when turning from left to right or right to left, doesn't seem to center, if I turn a little to left or right it stays there. I can go in complete a circle. Raised front off ground turns ok no binding, nothing loose on the front end.
View 1 RepliesI 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.
I bought a 2002 F250, 2 months ago love the truck drives great for 130000 miles, but the front left steer is making a lot of noise and wearing on the inside edge and like its skipping every couple inches so very noisy thought maybe ball joints but a buddy say tire is out of balance truck does not pull left or right and drives straight...

View 2 RepliesI have a 97 F250 that is having reoccurring brake issues, It has an intermittent hard pedal with little to no brakes when it occurs. It will stop but you are standing on the pedal with both feet. I have replaced the booster, master cylinder, and the vacuum pump in the past trying to isolate the issue and still had the problem. On this year model the abs ids only on the rear correct???? if it is shouldn't it only be affecting the rear brakes? Since this truck has a dual reservoir MC the front should still work?
View 4 RepliesThis is on my 2002 Ford Excursion 4x4. I have replaced the brakes 2 times with the same results.
New: rotors, pads, calipers and grease the caliper slide pins so they are sliding properly. I have also replaced the slide pins the first time. I even lightly greased the ends of the brake pad back plates where they mount in the calipers/brake clips. There is always more brake dust on the left front wheel compared to the right front. The steering wheel turns to the left when I hit the brakes. I can't figure this out.
The one thing that seems strange is it was very difficult to get the pads and brake pad clips into the caliper. It almost seems like the pads are too tight into the clips/caliper. I am wondering if taking a little material off the ends of the brake pad back plate to allow better movement in the caliper/clips.
The left front is either grabbing too much or the right front is not grabbing enough.
A few months ago I bought a used 2008 Mazda3s sedan, and ever since I get an intermittent burning rubber smell from my rear left wheel. I recently got new tires, brake pads, and had the rotors turned, with no change.
The smell does not always happen, it will be there maybe one out of 3 or 4 times, and it is more likely to happen after long drives (e.g., one hour highway driving).
The wheel well also feels very hot. The obvious answer would be that the brake caliper is sticking, causing friction, heat, and the burning smell. However, if I touch the rotor it feels the same lukewarm temperature as the other three.
One additional thought is that this is caused by the exhaust, which is right next to this wheel well. I have noticed that the area of the floor of the trunk right above the exhaust gets very hot, which I had not seen in any other car I owned.
Could it be that the exhaust is causing the rubber of the tire (or something else) to overheat and smell bad? Visually, it does not look like the tire has a different wear or different appearance, compared to any other one.
This may or may not be related: my handbrake seems to be useless If I leave it on I can easily drive with little to no noticeable slowdown... I guess the previous owner did not read the part of the manual where it says you have to release the handbrake before you drive.
I got a 2001 f350 got a noise in my left front wheel i know its not the wheel bearings, it only makes the noice when the locking hub is unlocked i did jack the the truck up and spun the wheel got a faint grinding noises form what seems like the locking hub so my question is bad locking hub or needle bearing holding the axle shaft??
View 3 RepliesHere's the deal:
* Drive the truck after it's been sitting a while (overnight, or at least a couple of hours), everything's fine. Good brake pedal feel.
* Drive 10-15 miles, stop-and-go at lights and stop signs, the brake pedal slowly goes from normal to firm, to very firm. Then, no play whatsoever and brakes are dragging bad. Yesterday, they were dragging so bad that I had it pulled into 1st gear with pedal on the floor just to get thru an intersection.
* Get out and check each wheel, all 4 brakes are dragging. I can tell from the heat pouring out of each wheel. And I've verified with infrared thermometer. Also, I've raised the vehicle when this is happening, and all 4 wheels will not turn. So it's definitely all 4 brakes.
At first, I assumed it was seized slide pins. But I've THOROUGHLY cleaned each and every one, and lubed with synthetic caliper grease. When the brakes are feeling normal, I've had my wife pump the brakes while I watched the calipers. Near as I can tell, they slide easily. Again, when my problem happens, it's all 4 wheels SIMULTANEOUSLY. So I've pretty much ruled out slide pins.
The brake pedal itself isn't getting bound by anything. It moves freely and I've lubed each of the pivot points. No problems there.
* When the brakes are dragging, I can crack the bleed screws and some fluid will come out at each wheel, which releases the brake at that wheel and I can then turn each wheel freely. So, there's residual pressure in the lines. I replaced the master cylinder (twice actually). No change in behavior.
BTW: I thoroughly bled the lines after each of the two master cylinder changes. I must've put 60+ ounces of fresh/clean/new fluid into the system so this isn't related to old fluid.
* Next, when the brakes are dragging, I can unscrew the master cylinder about 1/8-inch or so from the booster, and the brakes immediately release. Again, indicating residual pressure in the lines. So, I assume that something funky is going on with the brake booster. Also, when the brakes are dragging, I can pull the vacuum hose from the brake booster. And after a few seconds the brakes release. So I installed a new brake booster (re-manufactured one from NAPA -- they didn't offer a brand new one). No change in behavior.
After swapping the brake booster, I can still pull the vacuum tube when the brakes are dragging and it'll release in just a few seconds. So, it really seems like something is going on with the booster, but I can't figure out what it might be.
It is possible for the brake booster vacuum tube to have TOO MUCH vacuum, thereby causing the brakes to be unknowingly applied? Is there maybe a regulating valve of some kind in the line?
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...).
What is causing the right front wheel bearing to keep going bad on my 06 f-150 2 wheel drive....
