Ford Brakes/Suspension :: 2001 F350 - Randomly Screech Or Squeal For A Few Seconds Or Just One Time
Apr 20, 2012
My Superduty will randomly squeel for a few seconds or just one. It seems to happen randomly. The hub doesn't have play.

View 1 RepliesEvery time the dew point is up (that happens nearly daily here in WA) the brakes squeal the first time I step on them. After the 2nd stop the squealing stops. Service center has said that it's the brakes themselves; that they are steel and so develop rust and that causes the squealing. Can I replace these brakes with something that doesn't squeal?

I have a 2001 Expedition (5.4L V8). The ABS light has been on for some time. I finally got around to reading the code, and it reported "B1185 - Antilock Brake System Power Relay Output Circuit Malfunction". I have read and found information on the C1185 code, which sounds similar, but very little on the B1185. Not sure what to try.
What I have done thus far is replace the rear ABS sensor that is located on the rear differential. No change. I also replaced all four rotors and pads, but that was due to a pulsing during braking caused by a warped rotor. The pulsing was cured after replacing the rotors, but the ABS light remained unchanged. I removed both front wheel ABS sensors, and thoroughly cleaned them with brake-parts cleaner. Still no change. I have checked the fuse under that dash for the ABS system, and it is fine.
What to try next? I really didn't want to just start blindly shotgunning parts because I don't understand what B1185 really means. Perhaps someone else has seen this on their truck/expedition?
2001 F-350 / 7.3L / 147K ... What are some symptoms of the master cylinder going out? And is there a such thing as a rebuild kit anymore? The pedal has been getting spongier & spongier over the past months. Truck still stops O.K. but you have to brake earlier than I used to. Pedal can go almost to the floor. Pedal continues to go to floor as pressure is applied. Does not go to floor though.

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'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 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?
On the way home tonight, the Ex started to make what I can best describe as a screech/squeal. It sounds a little bit like a pulley spinning against a stuck belt or a motor that ran out of grease. I heard it 4 times and it lasted about a second or 2 each time. It seems to be coming from under the hood. The only common variable between all of the occurrences is a speed between 5 - 20 mph.
Belt has been replaced recently, when I looked under the hood all pulleys were spinning normally. The only thing I can think of is maybe it's the re-manufactured power steering pump that I put in after the redhead box install or the a/c compressor. When the compressor is running it makes a ticking noise. Maybe it's finally done and the screech is it starting to spin up when it engages the pulley?
I've been experiencing a loud clutch squeal or screech when I first engage the clutch after the car has been sitting for longer periods of time, overnight etc. It goes away after a few shifts and only returns after the car sits for a long period.
I brought it to the VW dealership since I'm still under warranty for a bit. After two visits the have come up with two hypotheses without any evidence. They claim to have not heard it or found anything wrong visually.
1) it could be a rear main seal leak. Or leak from somewhere on the tranny onto the cultch. When I first drive it is burned or wiped away. After putting on the lift they found no evidence of leaks. So hypothesis two:
2) Thy flywheel may be developing a bit of a patina of rust. After the clutch is engaged a few times, the rust is gone and the squeal goes away.
2011 F-350 XL, I can hear a squeal coming from the front brakes when rolling forward slowly, believe the pads are dragging on the rotors. If I touch the brake pedal the squeal stops as it does when I turn the wheel. Took the calipers off and greased the slide pins and put it all back together, still got the squeal. What don't I know???

View 6 RepliesI was wondering if there was how to on doing the MC replacement? The brake pedal goes to the floor almost every time you press on the brake?
View 1 RepliesI have a 1999 F350 single rear wheel Superduty truck that will not allow the right rear caliper to fully release. I replaced the caliper/mounting hardware/pads/rotor. The problem continued so I replaced the rubber hose to the caliper. Problem continues. I'm thinking possibly the center rubber brake line at the differential (where it splits and goes right/left) but at this point I am guessing. Maybe proportionate valve but I know nothing about them.
View 11 Replies2002 Sante Fe, 2.7L Belt squeals for about 10 seconds when the vehicle is first started up (engine cold) in the morning. Doesn't do it any other time until next morning. I had this problem 6 months ago and replaced the belt (OEM) and Dayco Tensioner. Now I have same issue again! What gives?
View 6 RepliesBrake pedal to the floor... And a lot of fluid on the ground.
I was coming home (empty fortunately) last evening when I noticed the brake pedal give an initial resistance, then slowly sank all the way to the floorboard when slowing down to turn onto my street. When I got to the house, I noticed a hissing sound each time as the depressed brake pedal sank to the floor. When I got out, there was a lot of brake fluid on the ground on the left rear side. It appears to be between the fuel tank and frame rail. From the side it is the section between the fuel filler to just ahead of the left rear wheel. The tank and frame rail is drenched and dripping DOT 3.
I am lucky to not have been pulling my 5th wheel when this happened! However, I have a camping trip coming up in a few weeks, but now my TV is broken. What has happened, and an estimate for repairs? Where is the best place to have it fixed, dealer or specialty shop? I just bought this vehicle in January and it has 102,500 miles, and came complete with full and meticulous repair records. The P.O. was incredible at upkeep, so this is something curious and flukey to me. But do I need to worry about the other side now, too?
Truck 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.
1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cylinder need rebuilding or is my vacuum diaphragm going. Not sure that's what its called.
View 7 RepliesLast weekend I did a rear brake job on my 1997 F350 4wd diesel. I replaced the shoes, replaced all the hardware, replaced the cylinders and had the drums turned. I have driven the truck all week and everything has been fine. Tonight while out of town I set the parking brake to see if it was any better since the rebuild, and it was. Shortly after releasing the parking brake I drove about an hour to get home. When I arrived home by driver side rear brake, wheel, etc. was very hot. I threw water on it and it turned to steam instantly.
I suspect that setting my parking braked hard like I did (like you're suppose to) somehow caused it to drag. What is causing this and what needs to be done so that it doesn't happen again?
After reading some other posts I went out and checked my parking brake cable and found that it is not bound up that I can tell. Perhaps it did not completely release although it seems to release just like the other side. I checked it from front to equalizing bar and it is in great shape. The plastic coating is still on the wire and there isn't any corrosion the entire length. The only thing I did differently on this trip vs the one I made two days ago was try out the parking brake before I left. The last trip I could barely feel any heat on the rear wheels when I got home, this time the driver side was scorching hot.
06 F350 with diesel and 6000lb springs. Installed bds leveling kit and the truck sat level. Then i bought a plow and mounted it. Well after this year the nose is down a little bit so i decided to buy new springs. I upgraded to the 7000lb springs, icon adj trac bar and dual stabilizer set up. Truck is still nose diving. Is there something that could be binding up?
View 1 RepliesI have a 2002 Nissan Sentra (manual transmission). I recently started noticing this horrible metal screech/squeal/scraping sound when my car starts moving from a stopped position. It's the worst when the car starts moving after it's been still for a bit. I thought it was due to the cold weather because when it started getting warmer, the noise issue went away. Unfortunately, the weather is warm, and it's back in full force.
The noise almost sounds like the noise that some semi-trucks (or large buses) make when they press on the brake. But my car only makes the noise when it starts moving and it only lasts a few seconds. It also doesn't happen every single time, which makes it even more frustrating.
I've got about 115,000 miles on the car...
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?
