Ford 6.0L Power Stroke Diesel :: Rear Brake Calipers Hung While Traveling In Mountains
May 30, 2016
Both of my rear brake calipers hung while traveling in mountains. Both so hot that I had no brakes. Had not been riding the brakes. Had to bump them when someone pulled out in front of me. Never noticed them hanging but smelled them and then hit the brakes and no brakes. They were so hot that they blew the valve stems out of both rear tires. Once they cooled, I had brakes. What would cause both to hang up at the same time?

We had approximately 7000 miles on our 2014 250 when we first heard our squeaking when we applied the brakes. This happened after we had been driving a while. Took it to the dealer to see what was causing the noise. They found out it was the front brakes. They removed both front wheels to find the inner pads wearing at an angle and the caliper piston boots partly melted in middle. They ended up replacing the brake pads and calipers with new and machined rotors.

Any clue as to why when im sitting at idle or at very very low rate of speed my A/C seems to work like a charm, but if i am traveling down the highway or basically anything above 40mph it seems to die down, like doesn't even keep me that cool..

Recently I had a radiator hose split while traveling. The EOT got up to 250 degrees before I could pull over and stop the truck. I flushed the cooling system with water, replaced the thermostat, and added Ford Gold coolant as per the recommendations in the Tech folder. My oil temps are higher now than prior to this incident. Unloaded on a flat road my deltas are about 10 to 12 degrees @ 60 mph.
My water temp will stay around 190 to 195 degrees while my EOT have reached 212-215. I pulled a small utility trailer and saw a delta of 17 degrees this was at about 75 mph. Typically unloaded I would only see a delta of about 8 degrees and this was at 80mph. My question is do you think a EOT of 250 would burn the oil, I had Shell Rotella T5 5W40 in the engine. Would it be possible that the oil cooler is partially plugged from this temp?

4450 - Literature Program 09L02: Customer Maintenance Reminder
Some owners of certain F-Super Duty 250/350 4x4 vehicles have experienced severe steering and front wheel vibrations and oscillations after traveling over a bump or dip in the road. As a result of a study with NHTSA regarding shimmy, Ford sent a Customer Maintenance Reminder letter to owners back in March of 2009. In addition, Ford agreed to send reminder letter to owners.
Although there is no service action required by the dealer, customers will be informed if after setting the tire pressures on their truck to the Ford specified levels, they believe the vehicle needs additional service, to contact their local Ford dealer. Letters will be mailed starting the week of 12/09/13 and may result in increased customer service inquiries.

Have to do a brake job on the truck? I took mine truck in for a CEL (New EGT 12) and during the Multipoint inspection they saw the brakes were pretty worn (and wanted an upsell im sure). I only have 49k miles and the fronts only have 20% and rears 30% of the pads left. So I get to spend a few hours this weekend doing the deed. Anything special to look out for?

I bought new pads for my truck and the fronts went on with no problem at all, but when I got to the rear the tabs/ears on the pads are about 1/8 inch wider than the notch they are supposed to fit in. I bought part number BR-1067, which is supposed to fit but obviously doesn't. What part number should I have bought? My truck is a 2007 F250 Super Crew Lariat FX4.

My left side rear blinker/ brake light is not working. The running/taillight side/filment of the bulb works, but the brake/blinker side/filament does nothing ! Just bought the truck used and it's my only issue, waiting on a owners manual, but I think each bulb is fused separate, and since half the bulb works, can I rule out the fuse and start chasing wires ??

Just over 7000 miles all of a sudden I got this loud grinding noise in the rear end like a brake locked up. Pulled into a parking lot. Don't think it's brakes. Put the truck in reverse it got even louder for a second then it quieted down after that. Naturally this happened on a Saturday.

A few weeks back my rear drivers side wheel started smoking severely...when I stopped you could smell the brake material, feel the heat coming from the wheel, and lots of smoke. I speculated it was the parking brake that got hung up. I jiggled that cable around and then went around the block - no issue. Note: I did not leave the parking brake on.
It happened again a week later, but not as bad. I took it into the dealer today. They said heat was evident as it burned off a sticker on the disk or caliper hsg area. They have not determined yet if it is parking brake or caliper?

My 2012 diesel frequently stalls momentarily after I touch the brake. This is very annoying as I drive in heavy traffic and often have to touch the brake then accelerate to merge into freeway traffic. The dealer service department said this was a 'feature' and not a flaw. Is there any way to eliminate this issue?

I currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?

I'm a mechanic but work only on cars so I'm a little shy on diagnosing trucks. I have a 2001 7.3 f250 4x4 short bed, when I give it gas I can hear a clunk, when I let off of the gas I also hear a clunk. Also when traveling at high way speeds I can feel a strong vibration when I very lightly give it gas but the vibration goes away as I give it more gas.

I noticed the aftermarket controller in my 03 F350 is not working. I am wondering where the fuse(s) might be located. Under the hood? Are they fuses or relays?

Is there one thing that when broken makes both the steering and brakes lose all power? Does the power steering and hydroboost share a pressure source?
My brake pedal is dead and I get no steering boost, but the master cylinder and PSP are full of fluid. Do I replace both, or replace one first to see if that fixes both? Or could it just be a hose leaking? Not sure how to diagnose this one.

I intended to use my 2006 4.6 v8 Explorer to tow my driftboat/trailer with a few tires over the Cascades and Rockies this weekend. I hadn't even made it from Seattle to Snoqualmie Pass before I decided to turn around.
My guess is the driftboat/trailer with tires was still no more than 1500 lbs and probably closer to 1000. Those of you who tow with yours, should I expect high revs to maintain 65-70 going up mountains with this type of load?
If not, what should I check? My 2006 Limited is AWD with 18 inch wheels. The tires are slightly larger than stock size.
NOTE: I took it to Montana using a F450 instead. Obviously, a bit overkill for a light towing load.

I don't seem to be able to get my trailer brakes to activate to we're I feel the working as the brakes are applied. I like the trailer to come on sooner and feel the trailer braking a bit more than the truck. I try the slide control and I have to go just about 3/4 of the way to get any braking on trailer. I had same with the 2011 and now the 2013. This a new trailer as was the previous trailer and the braking was the same. Trailer brakes are adjusted. I have it set on 10 as I did on the other truck. The other truck was 2011 and a trailer was a 2012 both new, now this set up is a 2013 trailer and 2013 truck and no difference in the two braking on the trailers. Are they all like that? I have installed brake controllers in my trucks and never had an issue not having enough adjustment for the trailer.

Was out on a camping trip. Went to move the truck and it acted like the emergency brake was on. I put it in and out of park 3-4 times with the same result. Noticed when I took my foot off the brake, it went from 1st to 5th. One of the guys in our group said to turn off the truck, wait 10 seconds. I did and all is well again. There were no CEL lights or anything.
Have 2700 miles on my 2011 (bought new May)

2003 F-350 dually. The brake lights will come on briefly then go off while the truck is sitting parked. Replaced the brake light switch on the pedal and it still does it.

Ever since I picked up my truck (350 6.7, c/c, srw, lb) I get a "bounce" in the back of the truck right at 40 mph and it stops right at 45 mph. My first thought was that I have a bad tire. I have 18" Continental A/S tires on it. The bounce gets progressively worse if I stay between 40-45 mph but clears right up if I slow down or speed up out of that speed range.
This week I took the truck in because of the change oil light came on with only ~1200 miles since oil change. I finally remembered to tell the service department about the bounce. They had my truck for 3 full days and all they have managed to do is confirm my complaint, not fix it. They road pressure balanced the tires 3 times and they still had the bounce. They called the Ford hotline and were told to take the tires off of a brand new lot truck and see how they were. The bounce is still there with the brand new tires.
The bounce is unaffected by rate of acceleration or gear the tranny is in... it just happens at 40-45 mph no matter if I drive like my granny or a jack rabbit. I have heard comments like "its the nature of the beast" but I don't think so.
I took my truck back for the weekend but the tech is waiting on another reply from the hotline as to what to do next. Since the new tires didn't work my next guess is the drive shaft or rear end since it is definitely speed related. I just realized that I don't think I notice it when I am hauling my 5'er but I am not 100% sure about that.
