Ford F-150 - 1997-2003 :: Front Brakes Dragging Only In Prolonged Stop And Go Traffic With Hot Ambient Temps
Jul 24, 2008
On a 1998 F150 2 wheel drive 4.6 250k, the front brakes will drag under a specific set of circumstances; only in prolonged stop and go traffic with hot ambient temps. Rotors, calipers, rear shoes, drums, fluid, bearings, seals have all been replaced. This occurs only a couple of times a year, otherwise the brakes work perfectly. It starts out as a slight shimmy that worsens until you can smell the pads cooking and the wheels are hotter than hell. The truck will hardly move at times. The rears are normal. After the truck cools for hours, no symptoms.

I have a 99 f150 4x4 that has done this twice, once last year and once this year during hot (90+) weather. I'll notice the vehicle seems like it doesn't want to go. Park overnight and it will work ok. Last time it happened the other day I stopped at wally world and both front wheels were real hot and I could smell the brakes. Came out hour later and when I pushed the brake pedal to put it in gear the pedal went to the floor.
Pumped up pedal and drove off but truck would barely move, drove 10 mph to a buddy of mines shop and it sat overnight and worked perfect the next day. He inspected everything and seems to think it might be the abs control unit. He noticed a small amount of fluid had come out of the unit and dripped on the ground. Also no abs light or brake light has ever come on

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.

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 have a 1999 ford f150 with 4.2 and 156,000 miles, about a month ago I drove from my house to a friends house a few hrs away. On my way home I started smelling a burning smell and stopped and my brakes were smoking. So I replaced brake calipers and still they drug then I changed brake lines and I can still only drive a few miles with out them getting really hot and dragging....

My husband bought a 1997 Ford F150 and the seller said he changed the brake lines, but the back brakes have dragged on takeoff since he bought it. Just put new shoes on it and it's still doing the same thing, but now the drums are getting hot. Is it possible that the seller got the brake line backwards and that might make the back brakes drag?

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.

2003 Santa Fe 3.6 V6 with ABS
The car sat virtually driven for a year before it was given to me. After 2 weeks of normal driving this past December, the power brakes completely went out. Had to drive the pedal to the floor to stop at even slow speeds. Took the mechanic and they replaced the Master Cylinder and both brake lines.
Shortly thereafter had an unrelated issue with a coilpack gone bad. Replaced coilpack and at that time replaced both sets of brake pads on the rear.
In January, started noticing grinding metal on metal from both front brakes. Took the mechanic and they replaced both calipers, rotors, and pads.
2 weeks or so later, after 10 minutes of driving the front brakes started dragging. The pedal would become extremely hard, and I could notice thew smell of the pads burning. Would have to pull over, put the car in park and pump the brakes to get the calipers to release. This would occur intermittently every few days. Pumping the brakes would always solve the problem.
Over time, the issue became worse, ocurring far more frequently. Around this time I noticed leaving the engine on in park while pumping the brakes would no longer solve the issue. I would have to completely turn the car off and pump the brakes to get them to release.
Started noticing around this same time that the left rear started grinding. The brake pads completely wore down in 3 months time. Too to the mechanic. Replaced caliper, rotor and pads.
Still having the same issue with the brakes dragging. One mechanic thought it could be ABS related and advised me to pull the fuse and the two breakers to diagnose. Still had the same issue, so put the fuse and breakers back in.
No mechanic seems to know what is going on with it, and I'd hate to have to replace all the brakes again as the problem goes untreated. Is it possible that the master cylinder or brake booster could be the issue? It's a brand new master but that doesn't necessarily mean anything, I'm told. Again, I can only get the brakes to release the pressure by pumping the pedal with the engine off.

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?

1998 FORD E350 CLUB WAGON 15 PASSENGER VAN. Front brakes are sticking bad. Stop at intersection with snow or slick condition and you can barely get the van to start moving. After you do you can fell the drag and the vehicle working hard to keep moving. Take tires off front, can not see anything obvious that is wrong. Can see where the bake pads are leave makes on the rotor.

My 2007 has been having this issue for the last couple of years and has gotten pretty consistent lately. When it's below about 60 and the engine has cooled to ambient temps, it will crank all day and not start. Once ambient temps are about 60, it will fire up and runs like a champ. You'd never know it had an issue. It's got a #4 glow plug fault. Other than that, everything is reading within parameters. FICM, GPCM, or what?

2015 Outlook 2.5 CVT - Regardless of engine temp/or oil temp, transmission will stay in low gears (relative - its a CVT) such that the car is always doing approx. 2100 RPMs. When it occurs, 35mph is 2100 RPMs; when problem is not present, same speed would be approx 1200 RPMs. Same for higher speed. 45mph would be 2100 verses approx 1400rpm. Gear indicator does indicate a '4' or '5' when it would normally be '6'.
Outside temps in excess of 30 degress - no evidence of problem. Below 30, may or may not happen. No check engine light and it does affect MPG significantly.

Truck is 2007 6.0L 4 door F-250 FX4
So this started after some High water encounters around my area. All freshwater. Went to the store and then i notice the truck pulling Left and got home and checked brake temps and the driver front and rear were over 400*F passenger side was 150* or less. No trailer no load in the bed. I decided to clean everything. Pads are worn but still have life.
Rotors showed some signs of where the pad is dragging Not bad though just a small area close to the top hat. I cleaned pads, carriage, and clips and reinstalled everything with some anti seize on the edges of the pads where the clips are and at the same spots on the carriage.
Thought it was ok but the after more water and a day or two sitting the same thing happened again. It is only the drivers side and it's both front and rear. I am stumped on this one. Two calipers going bad at once? I need to tow a boat on Monday So I have got to fix this.

The front brakes on my 2000 Toyota Sienna are dragging occasionally. I have replaced the front calipers (one of them twice), the master cylinder, and the ABS unit (with a junk yard unit). I have also shortened the master cylinder push rod to see if that would make a difference. The brakes still drag occasionally as indicated by the front hubs becoming excessively hot.

On said truck, when you go to stop, the brakes grab a bit, then release , then the pedal goes to about 2 inches off the floor, then they grab and hold. Pumping does nothing. No abs light on the dash. Today we put the truck in 4high and while back up I had full brake pressure from the top. Also when you take off, either in the mornings or during the day, it has a slight vibration, kinda like a brake grabbing, then all is fine. The brake grabbing isn't there 100% of the time, I would say 95%. I haven't changed the brake pads, rotors, or anything yet. Just didn't want to throw money at it and still not fix the problem.

I have a 2006 Subaru Forester with 115K miles. It's been well-maintained and well-loved.
For the past few months, the brakes have been inconsistently making a dragging/grinding noise when coming to a stop at low speeds (<5mph). It sounds to be coming from the front half of the car - I can feel it vibrating a little near the driver side. We've taken the car in to be looked at three times - each time, the mechanics think they've heard the noise and report there is absolutely nothing wrong with the brake pads or rotors. Twice they reported a shim was out of alignment. After the last shim adjustment, the noise got a little better - instead of grinding, it's more of a dragging sound now. Because the noise is inconsistent, I haven't been able to crack the formula of the conditions that produce it, other than that it only happens as I'm coming to a stop at very low speeds.
Is there something besides the brakes we should be having inspected? Does this sound safe to drive?

Had a problem with squealing brakes? My brakes squeal awfully when I am in stop and go traffic (in dry weather). Taken it to the dealer 2x and they've told me it will just do due to the pad having metal in it. I just have a hard time believing that my just over 1 year old car squeals like a dump truck..

My 2003 windstar SEL needed new brakes and to have the rotors turned... instead I opted to buy new discs and pads online ... To my surprise the new discs were about a 16th of an inch thinner than the old.... I changed discs and pads and was happy for a few days, but now on occasion when coming to a stop the front brakes grind terribly....the next time i stop everything is fine...visa versa...dscs feel true (no pulsing) I DID APPLY BRAKE QUIET TO THE BACKS OF PADS....

I have a 1997 F250LD 4WD. I was driving and came to a stop light. I hit the brakes and the pedal was rock hard with what seemed to be very little travel. I pushed hard to get to a stop and the abs activated and I came to a slow stop. This has happened about 3 times over the last 1000 miles of driving. I see no ABS or Engine lights. Most of the time the brakes are normal. Pads are fine, fluid is fine. Brake booster seems to work fine, pedal is not mushy or hard to press other than the 3 or so times this has happened. Once this happens I can let off the brake and everything is normal. I have not found any vacuum leaks.

What would cause my front disc brakes not to work. I have replaced the master cylinder, calipers, hoses and pads. Backs work fine but I can not get good pressure to the front. 1993 f150 5.0 ..

I had both front brakes lock up on me the other day and burnt the shoes out so I replaced the pads and installed new calipers and flex lines. I also went ahead and replaced the rear shoes and both wheel cylinders since this truck had been sitting up for the past few years I figured why not. I flushed the system out but I can not get all the air out of the right rear wheel cylinder. My question is could the new wheel cylinder be bad? The new left cylinder blew out when I first started bleeding the right side. I could not get any pressure at all and I looked over and seen fluid pouring out the left side. I put the old one back on only due to time restraints. Should I replace the right side again as well? I have used up 4 1/2 bottles of 3e2 oz brake fluid and still have air in that side.
