Ford Brakes/Suspension :: 1999 F350 - Brake Shoes Contacting Rotor (dragging) When Engine Is Off
May 12, 2013
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?

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?

I have a 2000 F350 4X4 with a V10 under the hood and a 5 speed manual transmission. It has a heavy western hauler bed, and a dual tired rearend. The truck has disc brakes all the way around that work great. I bought the truck used and immediately replaced all the disc brake pads as well as the seperate parking brake shoes and I had the parking brake drums turned. My problem is the parking brake shoes won't hold the truck at all and never have even when they were new. The parking brake shoes seem very small to me for a truck this size and weight. I have adjusted them as tight as I can with out causing them to drag when they are released. Is this a common problem for this type of parking brake on this type of truck? Is there something I am over looking or need to do to perhaps improve the parking brake? Would it be possible to splice some sort of "locking" valve into the brake lines going to the disc brakes to perhaps hold them engaged when I park the truck? I have a good idea how air brakes work, so I suppose this "locking" valve would work like that except basically opposite of a locking air brake valve, if that makes any sense.

I'm trying to replace the front brake rotors on a 97 Ford Explorer (AWD, 5.0 L). I've removed the calipers and pads - but can not loosen the old rotors. It looks held on by rust - but do I need a special rotor pulling tool?

Went and got new tires on the supercrew. Went going through parking lots or simply driving i hear a loud squeal like brake pad squeal. I put brand new wagner ceramics on the truck. Also if i turn to the left the driver side rear sounds like brakes are dragging against the rotor. Whats goin on with this. The squeal will happen between 10 mph to 20 mph and the grinding noise will happen if I am cruising or turning to the left. It goes away when i apply the brakes.

I replaced my front axle pads but the driver's side brakes seem to be dragging on the rotor making a very loud squealing noise when im driving. When I parked it in my driveway it was really hot and smoking. It doesn't happen to the passenger side. I pushed back the Pistons easily to get the brake pads in there so that wasn't a problem. But I must admit I changed them when my brakes were grinding.

My 97 f150 had been sitting for a while and after a few miles I could smell brakes and the left front rotor was hot. So I removed the caliper to see if I could free it up. When i push 1 piston in with a C clamp the other one comes out and visa-verse but I cannot push both in with 2 C clamps. When I push the brake pedal they both come out. Its like there is a check valve in the line. How should I go about trouble shooting this?

First it was the RH now after replacing the rotors, calipers and new shoes. The LH is now doing it. It doesn't stop the truck just gets hot, the wheel, and u can smell it. The truck is a 97 f150 ext cab 2wd short box, had since new and has over 200,000 miles and going strange until now. I want to get 300000.0 before I let her go. Had to replace a rear axle brake line years ago, and do not think the lines were bleed right, the brakes never work just right.

I've noticed when I'm towing, on long down hill grades if I touch the brakes I get what feels like a rotor causing the steering wheel to shake. At first it was only mild, but today on a long 6% grade it got really bad. Never does it on a level road, I've tried to duplicate it, only on a long down hill grade, and I'm not getting a pulse in the brake pedal at all, only the shake in the steering wheel. It's probably time to replace the pads anyhow, and I'll check the rotors. What things to look at?? 2006 F350, 6.0 dually 4x4.....

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.

I need to change the rear brake pads on a 2007 Expedition and was going to turn the rotors also. It appears the rotor is held onto the axle by a large nut and not having done any brake jobs in several years, I've never run into a rear rotor that's bolted on. Is this the case and if so, what size socket do I need to get it off. Also, I was curious if there is anything else I need to know before I dive in. I heard it was difficult to get off.

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.

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.

I am having trouble big time getting air out of my brake lines. I put new front pads and rotors on and also had to replace the brake line coming from the caliper as it kind of crumbled and needed to replace the next line up that goes to the ABS block on the left front. After doing this, I bled that wheel only and at first it was ok until the brake line on the right front at the caliper also broke when I was pushing on the brake pedal with the truck running, spewing fluid all over. I have tried to bleed using a decent vacuum bleed setup from Advanced Auto but keep getting massive amounts of air coming out and when I start the truck and hit the brake pedal, it goes to the floor. Could the master cylinder be bad? I have checked every connection that I made and all other connections and there are no leaks at all. I am stuck in the garage! The truck is a 1999 F150 4x4 with 4 wheel ABS.

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?

I have a 1994 F-250 4x4 w/manual transmission. I was driving a few days ago when the brake pedal suddenly went to the floor. I had almost no brakes (less than 10% at most), but luckily was able to get off the road safely. It was immediately apparent that the line connecting the T-fitting and the passenger side drum had broken.
I have never blown a brake line before, but I always assumed that you would have either front or rear brakes, depending on which line blew. Unfortunately I was wrong! The master cylinder reservoir was about 3/4 full when I initially checked it, but after I moved (slowly) the truck to a safer spot in the parking lot, I checked again and it was nearly empty.
Is my brake system behaving normally (no brakes front or rear, blown line completely empties the reservoir), or should there be some safety factor built in? If the system is operating correctly, is there any way to convert to a system that doesn't give out fully when a line is blown?

I just replaced the front break pads. I didn't replace the rotors or get them machined, didn't look like they needed them. Once I pushed on the brakes (truck off) I noticed that brake fluid spilled out the brake reservoir. I'm guessing it happened when I compressed the piston into the caliper? I took some of the fluid out of the reservoir and now its at MAX (I didn't bleed them). I've only been only be able to stop and go on the driveway (I'm waiting on a new radius arm bracket). The brakes seems spongy, the brake hits the floor. ABS and Brake lights came on then turned off once I started to pump them when I turned the truck 'on'. Do I just need to actually drive and "break" the breaks in?

I have a '99 E350 van that I am feeling a light anti-lock brake pulse in the pedal when I am rolling to a slow stop under light braking. Braking doesn't seem to be affected, but it doesn't feel right. I tried locking up the brakes and didn't feel any anti-lock pulse...seems backwards.

Before I get started... My truck is a 2006 F-250 Super Duty XLT 6-speed 4x4 with a Limited Slip.
I just got finished with a big job on my truck. New pads all the way around, turned rotors, new emergency brake shoes, hardware, and backing plate as well as replaced the rear wheel bearings both inner and outer as well as the axle o-ring and inner seal. Also, took off the rear pumpkin cover painted it and put fresh fluid in, went with Mobil 1 75W140 LS.
Took it for a drive and the brakes work great. Followed the directions for breaking in the emergency brake which worked fine.
Now the problem is I'm getting rattling from possibly all of the wheels. Definitely from the front driver and at least one of the rear wheels. It was so dark I didn't get a chance to look at it I just pulled it back in driveway.
I'll start looking at things tomorrow but, any common mistakes or things I should check first?
