Ford - Excursion :: Slightly Warped Rotors But Shakes Without Braking
Feb 10, 2011
Recently bought a 2001 Excursion 4x4 but failed to take it on the highway and get it up to speed. It shakes real bad around 65 but I can't tell exactly where the shake comes from. Here is what I've fixed so far. Balanced tires, Alignment, Fixed Steering Linkage, Balanced rear drive shaft, new shocks, new brake pads (slightly warped rotors but shakes w/o braking), lubed everything, replaced all fluids except transmission which was clean, no metal in any fluids, removed front driveshaft. Checked wheel bearing as best as I can.

So my 07 with 125k miles has had new rotors for about 50k miles or so, but for a while now when the brakes get hot it gets a violent shudder on braking at highway speeds....the odd part to me is nothing at lower speeds, and not always at higher speeds....do I just have warped rotors again? The rest of the front end I good and tight....

My brakes sometimes feel like the rotors are warped. The problem is that it isn't consistent. I remember how the original rotors warped and they were crap so I put some drilled and slotted rotors on about 150,000 miles ago. Currently but not all of the time it acts like the current rotors are warped, the steering wheel will move back and forth, feel the shake in the vehicle. But today running a few errands at lunch, there was no wobble etc. I might go ahead and replace the rotors/pads but want to be sure that is the issue. Could it be the hydroboost on the 7.3? ABS?

It all started around 18,000 miles when I noticed a vibration under highway braking. I convinced myself that everything was fine for the time being and I would have the dealer inspect the brakes at my 20,000 service. Fast forward to the service and all four of my rotors were warped. The dealer turned them all and said I wouldn't have any more problems. The car sits at 28,500 miles now and I'm starting to get the same vibration sensation as I had at 18,000 miles. I'm definitely going to be bringing the car in for it's 30,000 mile service and I will bring up the issue again. What type of warranty is on the brakes as I hope they will replace the rotors this time.

I have an '09 Avalon with 34K miles. On braking we get a shudder. It's especially noticeable on gentle braking. I am pretty sure this is due to the brake rotors being warped or whatever the correct term is. Are these covered under warranty? I'm a skeptic and I feel sure the dealer will try and blame the tires but they are wearing evenly and are rotated every 5K. The ride is smooth when not braking so tire balance should not be an issue.

I have a 1997 F-150 4.6 Liter 2WD ATIt rides and brakes smoothly when not running the A/C. When I switch on the A/C it still rides and runs smoothly and still brakes smoothly at first. After a few minutes, when I brake, the front end shakes slightly. While not braking it's still fine.The problem doesn't go away immediately when I switch of the A/C, but does eventually. However, on rare occasion the front end will start shaking like I have a square tire, even when not braking. This never occurs when I'm not running the A/C. Pads and rotors seem fine, tires are good, on visual inspection. A/C blows cold and the clutch seems to engage/disengage properly.

I've put 6k on the truck since the dealership replaced the front rotors and pads but they started to warp a few hundred miles ago. I do have a lift and new 37" tires so I was wondering what rotor / pad combo works best for larger tires and towing. I was looking at EBC kits but I'm sure there are better and cheaper options...

Brake issues on 2005 F250. About 3 years ago during vehicle inspection the garage stated I need all for rotors on my F250. I had @40,000 miles at the time. Garage said rotors are a onetime use, no recutting them. So I got all new rotors. Prior to then I never even felt a wobble indicating they were warped. Anyhow now with 15,000 miles on them I have a huge wobble when I get on the brakes and it's 5x pronounced when pulling a trailer. I assume more warped rotors. If so, why? I pull a camper or car trailer maybe 7-10 times a year.
Now currently I am assuming its warped rotors because I have not had it "professionally" checked. I did have one occasion last August pulling the camper where I smelled the brakes being hot. The pedal got soft. After cooling it seemed ok and I flushed the old fluid and put in new. I have about 4100 miles since then and the warped feel just started about a month ago. I hate the thought of new rotors as I paid for new Ford rotors 3 years ago. Didn't want the Chinese crap from the box stores. I can't imagine how these would warp this bad after less than 15,000 miles, they are massive. Why they would so quickly?

So for the past few weeks, i was getting this weird vibration coming from my brake pedal.. When I am about at 40 mph driving and braking or even when I am slowing down with out braking it vibrates.. I checked my wheel bearings.. I don't think that it.. since my steering wheel is not shaking when i brake, i think my rear rotors would be warped..
Also my idle is weird on my car.. I switched my coils and plugs.. it jumps.. really slightly and there is a big one.. when I opened my hood up there is this weird noise like a rattling noise and that is when the idle jumps up and down.. something like this [URL]....

My question is I have a 2002 Excursion 5.4 2wd with 126K on it, I have been chasing a shaking steering wheel while braking at higher speeds 50 mph and up, it is stronger at higher speeds and gets weaker and eventually goes away when slowing under 45ish mph. The shake in the wheel does not pull the truck at all, you can let go and it still stops straight. I have aligned and balanced I know its right I did it myself. I have also replaced steering dampener, and have done a full brake job on the front all new parts everything. Also the steering linkage is tight no slop or play in it.

I replaced my warped front brake rotors a couple thousand miles ago and all was fine but when I went to swap over to my snow tires, I can see that the outer part of the rotor has been rubbing on the caliper bracket. This is happening on both front rotors. Could my new rotors be too thick or something?

I have changed the rotor, inner and outer bearings, and the brake shoes look pretty good. My truck still shakes when I stop, it acts like bad rotors, but they are new.

Ever since day 1 when I make a hard stop i had a vibration when braking - heard i need to put bigger rotors on also change calipers - asked FORD about this and they said it would have to be aftermarket rotors and calipers ???

I have never experienced what others have described as the brake delay issue, neither before nor after the ABS recall. I have even purposely driven over rough patches of road to try to duplicate.
After two days of rain, I noticed yesterday that my brake rotors were rusty. I remembered a comment from qbee42 about putting the car in neutral while braking in order to remove regenerative braking and to force friction braking to clean rusty rotors.
Yesterday I was approaching a stop light with plenty of distance and no one in front. I started braking around 45 mph with regenerative braking and then pulled the shift lever to neutral. When in neutral and with the regenerative braking removed, I felt the decrease in braking when transitioning to friction braking and I had to brake a little harder in order to have the same amount of braking as before in regenerative braking.
I can see where someone can "perceive" this as a surge forward but I only interpreted this as a decrease in braking force, as others have stated here many times.
I tried this again at the next stop light and felt the same "sensation" again and had to brake slightly harder when in neutral in order to have the same braking force. It was apparent to me that for the same brake pedal position that the friction brakes do not exert as much braking force as the same pedal position with regenerative braking.
Is this similar to what others are reporting as "brake delay" or "surge forward" issues?

My 2004 Pacifica (130k miles) was left parked for 2 weeks while we were away. Upon return it didn't wqnt to back out of the parking spot. After about 1/2 revolution the wheels made a clanking sound and hung up. Rolling back and forth freed things up enough to drive the car to the mechanic (about 40 miles). And after the first mile or so everything seemed to go back to normal, with no absolutely signs of anything not wanting to turn smoothly.. The mechanic thought that the problem had been that the brakes were sticking due to the car being unused and said nothing needed to be done. However, upon examination he found that we could use new front brakes and 2 motor mounts. He said that the need for brakes and motor mounts was due to normal wear and tear, and was not related to the wheels hanging up issue.
But now, immediately after installation of 2 new front rotors and pads and 2 new motor mounts there is a vibration/shudder when braking from anything more than 20-30 mph, which was never there before. The shudder is rapid and sometimes pronounced like going over the warning groves cut into the edges of pavement on the interstate. He thinks that this may be a sign that there is a driveshaft issue, and dismisses it as due to an out of round rotor since they are new. I don't know what to think. By the way, he has always been an excellent mechanic, with a great reputation and loyal following.

I switched my front rotors 4 times in the last 4 years.
I know you probably thinking its the driver. I've owned the car since 2012 and have only put on 46000 kms.
The rotors vibrate and have that weird stop and go hesitation when braking.
Is it simply OEM or nothing?

Just had new front tires installed today and drove home. Car felt fine driving at 60 kph. Drove tonight on the highway and felt a bit of shaking. Its not as severe but can be felt sightly. Didn't feel this (slight) shaking with my old worn tires at highway speeds. What could it be? Btw, bought the car used last year at my local dealer and I haven't done an alignment yet since then.

Front caliper replacements--fwd? Person I bought this from said they'd just relined the brakes before I got it. After having it a week, I randomly checked torgue on lug nuts...a whopping 80 ft lbs. So now I have the vibrating rotors. When I back up I hear scraping like a bad set of bicycle brakes against an out of round rim. The pads are pretty thick. I bought new rotors and pads but I wonder if I shouldn't get calipers as well. This X likes to bite me in the butt--something simple is always about 5 times more complicated than anticipated.

Noticed the steering wheel shakes just slightly at highway speeds. Happens to me when I'm at around 65-70mph and above. It's just very slight, so I really wasn't thinking its an alignment issue at all. I didn't know if this was a bit normal for these B7s or what. I've had alignment issues in cars before and this just doesn't feel that bad, but its enough to give me pause.

I have an 03 Camry LE I4 with about just under 100k miles. Recently, under semi hard braking at highway speeds, the steering wheel will shake quite a bit to the point that I don't feel safe braking hard. I initially thought the brake rotors were warped, but those were replaced less than 2 years ago somewhere around 80k miles. I've taken it to many shops and here are the verdicts they've given me:
1. Rear drums are warped which is the problem (I don't think so...)
2. Control arm bushings need replacement (coming from shop who did brake work before)
3. Ball joints need to be replaced
4. All rotors should be resurfaced
What should I do?

I'm going to replace the rotors & pads on the X, was doing some research and read where slotted and drilled rotors actually create weak points in the rotor for vehicles this heavy.
