Ford Super Duty (1999-2016) :: 2003 - Front Brake Started Locking Up?
Jan 20, 2017
-2003 5.4 XLT. 178,xxx Disk brakes front & back.
Driving home from work, came to a long stop waiting for train. Started to drive away and my front right brake started to lock up pretty good on me. Drove it home as I was only a couple blocks away. Its just started to get above freezing here, and we've been between 0-20 degrees for a good stretch lately. That being said, I'm pretty sure it's my brake lines swelling with our "heat wave" of 35 degrees today. Also I've replaced the rear rotors & pads, as well as flushed the brake system a while back. Never replaced the front after purchasing used a while back, as they still had plenty of pad left.
Question : Purchased new front lines. Do the front calibers, "float" on pins like the back? (If so that may be my issue of the caliber getting stuck on the pins moving back and forth.)
At 178,xxx miles I'm going to replace the lines myself regardless of this outcome.

My hubs will not lock when put into 4x4. I disconnected all lines from the solenoid to both hubs and tested them for leaks... All good there. I put a gauge on the lines at both hubs one at a time while the other is still connected and get no reading when switched into 4x4. I checked for vacuum right out of the solenoid, and I get 2inHg when switched into 4x.
The vacuum pump kicks on every time I start the truck, even if I just shut it off and re-start right away. There is no delay when switching my ac/heater controls to different settings or vent locations. So I know there is vacuum. How much vacuum I should be getting out of the solenoid to the hubs?

I am considering buying a 2001 Ford F250 Super Duty XLT 4x4 V10 engine tomorrow. I am hesitant because I cant get the 4x4 to engage. It goes into 4x4 low and high and the front driveshaft spins but it wont engage the wheels. One side locking hub locks but the other side the locking hub is cracked off and so I there is no way to turn to lock that side. I will of course replace the Locking Hub ASAP if I buy the rig but my question here is, if one side is locked should one side of the front axle spin, meaning if only one side Locking Hub is locked should that wheel turn and the other not? Both are not turning but as I said the driveshaft is spinning.
I don't know if both sides need to be locked in order for the front wheels to engage while in 4x4 high or low. Or if one side should engage if only one side is locked; the wheel that's locked of course..

I noticed yesterday that my tire on the driver's side has rubbed a flat spot on the rubber brake hose. I bent the metal tubing so that it doesn't rub any more, but should this be of great concern? Obviously I'd hate for it to rupture, but it looks as though it's not too bad.

I've noticed my front axles are rotating all the time even when the hubs are in auto and supposed to be unlocked when in 2wd. Is there a rebuild kit for these so they will unlock the axles or do I need to buy new locking hubs?

I have a 2000 f250 4x4 with 4 wheel abs. The front passenger side caliper keeps locking up while I'm driving and won't release and when I hit the brakes it pulls hard to the drivers side. I have put two calipers on the passengers side and put new brake lines on.

Here's a new one. Driving along the other day and the back starts hopping. Stop to check and I notice that the rear brake is hot. Stop and wait for it to cool down and then look at the rear calliper, give a wiggle and it is free again. It then drove fine for a couple of days and then today, whilst driving down the road it starts to hop again. Stop and the same hub is hot. Only a mile home so drove slowly back to check it out. Thinking it is some muck got into it causing it to stick. (Living in the Rockies, lots of sand on the road at the moment to deal with all the snow.) When I get home found that front left wheel is cool but all other 3 are HOT!! The hopping started on a long flat stretch and I hadn't applied the brakes. Is it possible for the ABS sensor to apply the brakes when you are not using the pedal or is there another reason for 3 wheels to start braking?

I have a 2002 Ford F250 Superduty with a 7.3 diesel. Brakes started sticking on it. I replaced all the calipers cause the boots were starting to crack but not leaking. All four brakes are still sticking. I can drive a little ways and then the brake peddle feels funny and they start dragging all four. I can loosen the bleeder and brake fluid will spray out and release the brakes for awhile.

I recently purchased a 2003 F350 FX4 Dually with the 7.3L Diesel. It has locking hubs and electric shift in the cab.
I have had locking hubs before that you had to engage to shift into 4 wheel drive and I have had trucks without locking hubs.
My truck didn't come with a manual, so I am looking for instructions for the proper use of this system.

I replaced a rear rusted brake line a couple of years ago. It rusted where the line met the bracket. I'd never done this before but bought a flare (flaring?) tool and fixed it.
This week the longer line that runs down the length of the truck started leaking. It looks like the line was once held in place by a small bracket just in front of the rear wheel but it wasn't in that bracket anymore. I guess it rubbed against the metal and water/sand rusted it out.
A local garage said they'd need to drop the fuel tank and estimated that it would be several hours (and hundreds of dollars) to do the job. It looks like I might be able to cut the old one out and then fish the new line up through there and replace it.
Also, what is the diameter of the line? It is a 2004 F350. I can certainly cut it out first and then take a piece of it to the local auto parts place to get the replacement line.

Ive got a 2002 f250 Sd 4x4 with 93000. Im getting severe vibration from the front drivers side at highway speed. I thought it might be a warped rotor but i cant feel it in the brake pedal, when I put the brakes on. How can you tell when the hub bearing assembly is going bad? The truck doesnt pull to that side either. I can hear it, and feel it more when i'm going around highway corners. When im driving through town, I can hear a "clunk,clunk,clunk" noise coming from that side also.

I have been having some brake chatter for awhile now. I have changed pads, changed rotors, rebuilt both front calipers, flushed all my brake fluid, and made sure my slide pins were good and free. I have noticed some weird wear on the new front rotors and was wondering if it was normal or not. On a different note, I am having to replace my parking brake pads. When I had the axle out I looked in and saw a bunch of gunk.

2003 f250 5.4 86000 miles. When I start the truck, "especially after it sits a day or more" it starts to fast "Rushes". Like the gas pedal is all the way to the floor. I have taken it to the Ford dealer and they say they can find nothing wrong. They say all fords start up fast but I know this cannot be right. If I start it and let it run awhile then start it again it starts much slower. It only rushes like that a second or two and slows down. Today I noticed that when it started all the gauges pegged out. The speed indicator went up past 100mph sitting still in park. Then they all dropped down to zero then back to where they should be.

2012 F-250, it sounds like a rock or something in my left front brake cover?? I only hear it when I come to a stop or just start out, sounds like a stone or something coming to rest like if you had a stone in a drying machine coming to rest when you shut it off. But I don't hear it at all over 10mph?

Any good info on front brake replacement parts to get better braking out of these beasts? My pads are now needing replacement but I would like to get better performance than that of factory parts....

I read a reference to the front brake caliper bracket bolts being one time use torque to yield and must be replaced every time they are loosened. Is this true?
This is on my 06 F-350 in my Sig.

2001 F250 SD diesel. Brakes have been working fine with no pulling. They just started to squeal recently so I knew it was time for some new pads.
I'm having a problem that seems to plague me often when I try to replace disc brake pads. I can't get the twin pistons to go back in to allow room to get the new, thicker pads in.
I unscrewed the cap to the master cylinder and used a spreading tool (that came in a brake kit from Advance Auto Parts) to compress the pistons. No movement.
I put a lot of force on it. No piston movement.
I unscrewed the bleeder screw and tried again. No movement.

I'm gonna replace my front and rear brake pads. Any tips? Do I need to pull the rotor off and clean the axel? I've watched a couple of youtube videos but they leave me with a few answers. I have all the tools, what kinda lubricants will i need? Any recommendations? I hoping I can do a flawless job without and squealing...

When on my 2-post lift my front brake lines on my '11 4x4 are pulled TIGHT, like stupid tight. It's also dumb that the soft line points UP 'cause it gets tugged down to a brutally tight 180.
I've got the front lift pads under the control arms, too, but near the very rear of the control arms so the axle isn't even dropped out all the way I don't think.
There's a bracket down near the bottom of the coil springs that could just be sectioned/lengthened, which I think would alleviate my issue. I'll be working on this soon.
What manufacturer builds a vehicle that yanks on the brake lines under full suspension droop? Shouldn't this be on an engineer's final checklist before the vehicle is released? Oh wait, they gave that task to Team TTB and Engineering Group TFI Or maybe they gave it to the same Audi team that designed the Allroad with airbags that can be damaged if you don't "lock" them out before lifting the vehicle......

I know this has been talked about many times and how to solve the issue but thought I would ask some other questions too. Earlier in the summer, I did grease the slider pins as preventative maintenance. I don't drive my truck all that much and when I used it yesterday, (about 30 minute drive) I came home to burning brake smell. I'm wondering if enough heat would cause the caliper to go bad? Should I just grease the pins again or change out some parts?

F350 Super Duty sometimes the front driver side brake sticks and will pull to the left while driving and pull hard to the right while braking. It has a slight front end vibration when the symptoms are present. The wheel will be boiling hot to the touch and the smell of brakes burning is obvious.
After the truck sits, it will be good with no incident for weeks.
With the wheel still hot and on jackstand, the front wheel seems to turn freely until the brakes are applied, and seems to spin free again as brakes are released.
It seems to happen when I have a "hard braking" incident going forward until I park the truck and let it sit. If i consciously brake soft, the brakes seem to be fine.
I have read some of the posts and this is different in that it is intermittent.
I have replaced the brake hose as I thought it could be the "check-valve" symptom. No luck.
I have checked the sliders and re-lubed and they slide freely.
The caliper is relatively new and the fluid in the system is fresh as i recently changed the rear brake line and completely flushed and bled all four corners.
Do i just change the caliper, or, is there a way to find out if one of the pistons is intermittently binding? I would hate to invest in a new caliper if that is not the issue.
