Ford Super Duty (1999-2016) :: Odd Braking / From 5 To 0 MPH It Almost Feels Like Slide On Ice For A Second
Dec 14, 2011
First off I want to say my truck isnt throwing any codes, nor am I loosing any pressure on the brake peddle. What is going on is my brakes are working just fine I can stop from any speed and my brakes are performing just fine until I slow to about 5mph.
From 5mph to 0mph it almost feels like I slide on ice for a second, and you hear a sound almost like what you hear when your ABS kicks in. I will feel a slight fluctuation in the brake peddle and then my truck comes to a stop. It is the darnest thing. One mechanic I spoke to said he thought is was the vacuum system, another thought it may be the brake sensors....

I have a 1999 F-250 SRW 4x2. Is there a post that explains how to remove the front brake slide pins?

I bought a 2001 7.3L deisil F250 CC short box a year ago. It has an AFE cold air, a 4inch exhaust and an Edge chip in it, Now the tranny was rebuilt a year before I bought it, however I almost instantly noticed a shutter when starting from a stop. One shop said u joints. I replaced them and the carrier with no results. IMHO u joints was a bad diagnosis as it only happens off the line and not through at a certain rpm. When down shifting I find the truck almost goes into to neutral before engaging 2nd gear. I have a 6.0l tranny cooler and my temps get to 215 and above quite easily when towing... 3-6k-lbs. (I try to pull over before that) Also when towing up hills the tranny almost feels like there's a slight grinding. For the first little bit anyway.

I have a 2014 f250 with the 6.2 and just turned 13,800 miles. I tend to drive in tow haul a lot, while not towing because I like the shift pattern better and saves on brakes while stopping. Last night I slowed to a stop sign, came to complete stop. Went to take off slowly like always and the truck was like in neutral, looked down and the indicator showed 5th gear. Let off and watched it go to 1st and took off no problem. This all took only half a second or so, seemed fine after that. What might of happened?

So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?

2004 6.0L Excursion Limited 4x4.
I recently developed a "rumble" with vibration while braking. I describe it as a rumble because I associate it to a similar sound, cadence, and feeling as if you were slowing down on the rumble strips you find on the side of the highway.
It is mostly only noticeable at lower speeds. I know the sound and feeling of warped rotors, but this seems different. If it makes any difference, one issue I've been dealing with is that the front transfer case does not release when 4x4 is off and hubs are in AUTO.

Truck is a stock 2001 f250 7.3 with 205,000 miles. When accelerating or braking from about 40-60mph it starts to shake a little bit. When braking it shakes a lot more from 60 down to 40. But the faster you speed up the less it shakes when taking off. Looked at everything underneath is tight, and it has stock a stock steering stabilizer. Would a new stabilizer fix this you think?

While engine braking I started hearing a squeal under the hood , when I started accelerating it became a little louder, I pulled over and when I rev it up it gets louder and has a little rattle sound, sounds like it coming from the turbo....

.I just changed out all the steering linkages due to a lot of slop and worn out tie rod ends. This problem existed before I changed them but I thought for sure changing the linkages would fix it. When I brake hard my front tires wobble very bad. I haven't ever experienced the death wobble that is common in these trucks, but the symptoms seem the same, its just only when I brake hard. I can look at my front left tire while braking hard and see it wobbling. The wheel bearings and ball joints only have about 15k miles on them. I can't tell if the front wheels are moving independent of each other back and forth, or if they are both shaking back and forth together. What might cause this? it's a super uneasy feeling when it happens, especially because whenever you are braking hard there is usually a reason.

I've noticed that my 06 f350 will pump the ABS when pulling in muddy spots, mostly in 4x4? It will even start to cook the pads after a bit of spinning. I'm not doing any serious off-road stuff, just trying to pull random farm equipment/trailers. Do these trucks have some sort of traction control that I don't know about or dose my ABS think I have my foot on the brake all the time?

I'm having trouble finding the source of a vibration in the front end if my 1999 f350 super duty 4x4. The vibration is felt all the time but worse when under 40mph, while braking, and especially when turning.
I have replaced the rotors and brakes, tie rods and Drag links since the issue started but no change. In the vibration. What should I check next?

When braking the truck shakes terribly, enough to toss a drink out of the cup holder almost. Sometimes there is a slight feeling in the peddle but not always. The shudder feels like it is timed with each revolution of the wheels.
It developed from a perfectly stopping truck over the course of maybe a month. I don't drive the truck that much either.
Things I have checked:
1, all u-joints, they all look and feel good, no play or slop in them
2, air pressure in all tires, even rotated them, no effect
3, brakes-front and back all looked good but I went ahead and replaced front pads and rotors, cleaned caliper pins, zero effect.
4, shudder exists whether in gear and slowing or in neutral, 2wd and 4wd
What the heck else is there to check? My first thought was, front brakes/warped rotors, but after pulling them apart there was so much life left on the rotors and pads and replacing all that with new did nothing! Could bad back brakes cause this much of a shudder? They look fine as well.

So yesterday I drove across town and back to pick up a piece of lawn equipment. About a 30 min hwy drive each way. On the way there I was in stop and go traffic for about 15mins and noticed toward the end the truck would pull hard to the right when stopping hard and sudden. I figure it was my steering. Been having issues with horrible steering since my last alignment and adjusting the caster. Truck wanders, steering feels loose, will not fully recenter, and feels like it binds then releases toward center position. That's a different issue, I assume. I stop on the way to get some cash and everything is normal. Pick up the equipment and drive back. When coming to a stop the truck will pull towards the right and when I suddenly stop it now pulls to the left.
I get home and get out and smell something burning and hot. Grabbed my IR thermometer and hit both front wheels. Passenger is 150f brake rotor is 175f, drive is 280f brake rotor is 580f. So im assuming my caliper seized up or started to stick. I plan to jack up the front and look at the hubs and calipers. Any other test I can do to narrow down the culprit. I am thinking the hoses may be collapsing especially since I had to disconnect and flip them during the lift. Just weird that the hard pull would switch sides if only the drivers was sticking. Could my bad steering and brake issue be related? I have also noticed my braking power has dropped recently. Brake fluid looks good but power steering smells like brake fluid and is orange.
Pulled the tire when I got home today. A little resistance when spinning by hand, more than there should be. Pulled the caliper and greased the slides. Found out my hub is bad so those are on the short list now. Reassembled and had my wife hit the brakes while I spun the tire. Progressively got harder and harder to spin. Was looking at the brake hoses, how much should they move and ''shrink'' when the brakes are applied? Also if I hit the brakes repeatedly while rolling down my drive way the pedal gets harder and the truck doesn't want to stop and the pedal will slowly push all the way to the floor. Now I am just lost at what is causing my braking issue.

I have an '01 F250/4X4--How can you tell if your rear drum brakes are bad? Do they make a noise?

I have an '04 EX with 6.0. When braking at highway speeds the rear end shudders until I get the truck slowed down some. Around town speeds of 45 or less the problem is almost non-existent. It almost seems to be hydraulic instead of pads/rotor issue. Wouldn't a warped rotor show up at slower speeds as well? I have some good mechanics around, but have never found a great brake shop that I can trust. Go in needing pads and they try and upsell saying this or that is going out.

I have an 05 F250 Super Duty 6.0 V8 Turbo Diesel. This is my first diesel so don't know my way around it too much yet. I just don't know what could cause this problem. It sounds like a faulty sensor to me. But no engine light has come on. My oil pressure drops down to in the red zone when I brake while driving, then once I return to driving again it returns to the normal pressure. It's almost as if it has something to do with the tilt of the vehicle.

Truck seems to run ok, but when I push the brake pedal down a bit, a strange grinding/howling noise comes from the engine bay and same thing with the power steering. When I put the brake pedal down to the floor, it stops?

I tow 10-15K; 6-10x per month with this truck. I can feel the braking ability starting to drop off so I want to get them done pretty quick. I am more or less happy with OEM performance but if there is a better value, and with my SO starting to haul the horse trailer around.. I wouldn't mind upgrading.
What is worth the money? I'm fresh out of school trying to figure out what the best value is.
Calipers?
Rotors?
Pads?
Brake Lines?
What would provide me with a noticeable improvement without breaking the bank?
Last question, could worn rotors cause vibration/shaking in the steering (primarily when turning ramps) at 50-60mph? Tires are brand new, problem showed up before they were replaced.

My 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.

2014 F450. Front end and steering wheel shake violently when braking while towing a 20,000 pound trailer down a long and steep highway grade. It does not happen when towing my 12,000 pound trailer down the same highway. Could I be setting off the ABS braking system?

First off I want to say I love my 11 f350 6.3 srw she's a awesome truck. I pull a small 7x14 trailer for my biz..
(3600-400) is the usually weight, I always use my tow feature. One day last week I start out hit my button in go, but I notice the engine braking/down shifting wasn't working. The trans still shifts smooth n normal the light is on the dash but no tow engage.
I check the transmission wire plug to make sure it'd getting a good connection, it does. I take the rubber boot off next to the shifter look at those wires they look ok not pinch or nothing, so I'm stumped.
