Ford Brakes/Suspension :: 1999 F350 - Caliper Won't Release Fully
Jul 15, 2017
I 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.

2008 Ford ranger 4x4 fx4. Rear brakes drag just enough to notice, only when temp out side is below freezing. Replaced drums and shoes. stopped using emergency brake. Had wheel cylinders inspected.

I pulled a brake caliper off for inspection, and when I reinstalled it, I managed to strip one of the holes on the caliper bracket when putting one of the 7mm bolts back in - haste makes waste, ya? So, I am trying to find out my options, is it possible to get it re-threaded, helicoiled, or is it toast and I need to buy a new one?

My driver side caliper will not bleed fluid, is it safe to say that the caliper needs replacing.

I have a '79 F150 4wd and was wondering what would indicate a caliper needing replacement. I'm already going to replace everything on my rear brakes, they are completely trashed. However, the fronts seem OK, NO indications of leaks or seizing both sides of the rotors appear to be evenly "used" I guess. The inner pads do seem to be thicker than the outer pads is this normal? Anything I should be specifically looking for before I have the rotors turned and put a new set of pads on?

My 1999 F250 right rear brake caliper will not release. I replaced the caliper, caliper mounting hardware, pads, rotor, emergency brake pads, and I bled the system. For some reason the right rear remains activated when my foot is not on the brake pedal. The other three wheels appear to be functioning normal.

I changed over to summer tires today on my 1999 4wd F350 diesel . While the front tires were off of the ground, I tried rotating the wheels by hand to see what the resistance was like. I was surprised at how stiff they were. It would take three fingers to rotate the wheel and as soon as I stopped applying pressure the wheel stopped turning. I pulled the rims off and found that the calipers appeared to be contacting the rotors and causing resistance.
My last rig was a 1960s 4wd F250 that had calipers that could be adjusted manually. I kept these adjusted so the calipers were almost touching the rotors. I could spin the rims with one finger and the wheel would turn for 30 seconds or so until coming to a stop. Is this normal?

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?

Here'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?

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.

Last 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?

Bought a high mileage 99 f150 4x4 yesterday. In the process of cleaning her up, the water hose hit the disc brakes on the drivers side and it was hotter than a BBQ grill! Ok, immediately I thought this isn't good. Jacked her up and pulled the caliper. Pads were almost gone so replaced them with a new set, went for a drive. Now the damn things were smoking so bad I thought they were gonna catch fire! Sticky caliper , right? Stopped and got one then realized that the passenger side started doing it too.
Another trip for the other caliper and new pads because these were toast. I mean just burnt to hell. Before I started working on the truck again, I checked on here and I'll be darned if I didn't find out that the old brake hoses might be acting like a check valve because of rust and deterioration. Got a set of brakes hoses too. Put everything on this morning and works like a charm.

My Superduty will randomly squeel for a few seconds or just one. It seems to happen randomly. The hub doesn't have play.

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?

I 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.
