Prius (Gen 3) :: Front Brakes Dragging Excessively Causing Lack Of Power And Poor Fuel Economy
Dec 15, 2013
Our 2010 Prius just had the brake booster recall done and I also installed new pads and rotors. The car now has issues with the front brakes dragging excessively causing lack of power and poor fuel economy. There are no codes and everything else checks out okay, the brakes function fine. Is there anything on these cars that would cause brake drag after a new brake install? I just want to ensure there isn't something I can do before I bring it to the Toyota dealer.

I have a 97' hyundai tiburon, I have multiple misfires that are p301 302 304 and rich airflow. I have changed the coil pack, spark plugs and wires, and the MAF sensor. Basically my car doesn't accelerate fast or go over 40(max), it putters when i try to accelerate.

My 2001 L.L.Bean Edition H6-3.0 is losing power & MPG on the fwy. Sometimes it will feel like something is holding it back or dragging. I've checked the brake calipers and they're not sticking, changed the air filter, oil & filter, transmission fluid, and still cannot find the problem. I've overfilled the gas tank and read this can damage the charcoal canister. Will a saturated charcoal canister cause a drop in power and MPG? What should I check out next?

I have a 92 Dodge Spirit 2.5L non turbo. I have been getting horrible fuel mileage. Around 17. I have given it a full tune up, including replaced the distributor and hall effect sensor. Why my fuel economy is shot?

Was looking to get some input on possible reasons why I'm getting bad fuel economy. I have a 2003 Jetta TDI with 335 000kms and over the past few months have gone from roughly 1000km/tank (5.3l/100km) to about 700kms per tank (6.7l/100km). The cars timing is spot on. I've changed the air filter. Checked intercooler and maf all of which seem to be fine. I have a VCDS and have gone through many of the values and everything seems to be running fine except for excess pressure.
The map reading is spiking to 2500mbar at about 2800 rpm under full load. Specs on the vagcom say it should be around 2000mbar max. Power is fine and its not smoking other than on start up which on cold morning ( everyone morning here in Canada) seems to stutter quite a bit while idling for the first minute or two. I realize winter gas along with winter tires etc can equate for quite a bit of fuel economy loss but i just cant see losing 300kms / tank.

Blown fuse causing a lack of power to the OBD port?
I just got my Kiwi2 BT OBD2 adapter and was hoping to start diagnosing my truck, but the adapter won't power on while connected to the truck.
I pulled and visually inspected fuse #12, I also verified power to the cigarette lighter plug and the accessory 12v power outlet.
The adapter powered up with no problem when I connected to a co-worker's Tacoma.

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.

While driving my 1998 Chevy Prizm, my car lost the ability to accelerate but the car never lost power. I managed to pull over and let the car run for a bit before trying to accelerate again..the car only got up to 30 mph and wouldn't go any faster.....after a couple of hours the car run okay. What could be going on? I got new spark plugs, oil change, and an idle air control valve........

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.

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.

Every time I turn the car on, the "from start" fuel economy reading resets to 15l/100k. After driving for a while it goes down to 4l/100k but then resets back to 15 once the car is turned off. Is there any way to get it to stay at what it finished at?

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).

I am wondering about how fast to accelerate for maximizing fuel economy. I understand with the P&G approach that you don't want to get up to speed too slowly. The question is whether it really is more efficient to go ahead and get up to speed or stay within the ECO guidelines? In particular, I find that getting up to highway speed especially that it can take quite a while to get up to 70 mph without having it going into the power range. It seems like it is better to get up to speed and then back off to go to the high efficiency mode.

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.

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.
1999 4.6 XL
Passenger side done

I have a 2013 Prius V and my mpg averaged about 43. Now after about 13,000 miles it has gone down some to more like 41-42 and even 39. Once on a mostly highway trip it was down to about 34. Last summer it got 51 mpg in Colorado!
How to get better mileage. I once heard about a feathering technique with the accelerator but I don't know if I understand it.

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.

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.
