Ford F-150 - 1997-2003 :: 2002 - Brakes Pulsing In Front Like Antilock As If Braking On Ice
It's a farm truck, lumber getter trailer puller. Not driven often, after sitting for awhile the brakes seem to be pulsing in front like antilock, as if braking on ice. I checked both front caliper springs or plunger slides and they are free not froze up.
View 1 RepliesSubaru - Forester :: Pulsing / Crunching Sound From Front Brakes - ABS Light On
My 1998 Forester suddenly began pulsing / crunching sound, from the front brakes. I had just performed full brake inspection 2 weeks before. So I removed the ABS fuse (20 amp), and the problem disappeared. Of course the ABS light is also on now, but I can drive the car. I disconnected the 4 wheel sensors from the car harness, connected an oscilloscope to each, and spun the wheels pretty fast. I get 150 MV peak-to-peak from each sensor. Must I replace the "tone rings", or just wire-brush them? Replacing the rings are a BIG job, and the wheel bearings & seals must be replaced, since they don't survive pulling out the axles from the steering knuckle (front), or strut assembly (rear).

I have a 2009 Ford Focus and have been having a problem with the brakes. When I hit the brakes at any speed there is a feeling of pulsing as I slow down. It is proportional to the speed I am going. It feels like there is an unevenness to the rotor or brake drum that makes one spot on either of those hit the brake pad/shoe more severely than the rest of the pad/shoe and thus I slow down more during that one spot. Maybe the best way to describe the feeling is like this: While the brake pedal is pressed down it feels like I am slowly pulsing the pedal even though the pedal is steadily pressed down. This pulsing feeling slows down as I slow down until I stop. What might cause this?

Here's what I am running into. I have factory setup and it doesn't feel adequate. I get vibrations, lots of brake dust on front wheels, and just don't feel I have the stopping power if needed in emergency or towing. Especially with how heavy my 6.0 is already.
View 12 RepliesFord Excursion :: Squeaking / Odd Grinding Coming From Front Brakes
Replaced both rear calipers about 4 months ago, both were frozen. A few weeks ago I started getting some bad squeaking from the front brakes. The front calipers seemed fine when I did the rears.
Tonight I had even more fun with the beast. Drove to my sons baseball game and felt an odd "grinding" when braking. *Seems* to be coming from the front. On the way home, the grinding was worse and then the fun really started. Hit the brakes and the wheels started hopping enough to shake the whole friggin' truck. Leaving from a light, you could feel the brakes stick and then release, next stop was more shake n bake.
Not sure where to start on this one.
Ford Excursion :: Cannot Get Front Tires To Rotate While Parked And Stepping On The Brakes
Just bought a 2001 v10 ford excursion limited with 127xxx miles. I have a few questions.
1. I can't get the front tires to rotate while parked and stepping on the brakes. I thought it was caused by the 35 inch BFG goodrich all terrian tires and a lift kit i dont know how tall but apparently i'm just a sucker. From the searches i did, i think the problem is that either the power steering or brakes doesn't have sufficient pressure to power both at the same time. what is the fix to this?
2. I found metal shaving in the rear differential. For lack of picture, the best i can describe it is that it looks like shaving off an ice block. Also, the fluid is gray and consistency of sludge. I searched and some said the shaving is normal and others said fix now. Which is it? I assume that the rear differential fluid needs to be changed.
Ford Excursion :: Brake Intermittent - Hard Pedal And Pulsing Feeling Randomly
I'm having an issue with my brakes. It was very intermittent, but seems to be happening a little more often lately. 99% of the time they work fine.
I'll try to describe. (vaguely) It will sometimes feel like the ABS is engaging, get a very hard pedal and some pulsing feeling. Sometimes just the pulsing without the hard pedal. It will happen at random times. Today it did it in the driveway going 5 MPH. No reason the ABS should think of kicking in.
I feel confident to rule out anything downstream at the wheels. I am leaning towards the master cylinder, but maybe that's wishful thinking. Afraid it also could be something sticking in the ABS which I assume is $$$.
Brake fluid is 18 months old with maybe 20k on it.
Lexus GX 2004-09 :: Brakes Pulsing At Low Speeds
At low speed braking or before it comes to a full stop. I'm guessing the ABS but would like a 2nd opinion from others. If it's the ABS, is the fix something that can be done DIY?
View 5 RepliesPrius (Gen 1) :: Pulsing Raspy Noise When Brakes Are Applied?
Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.
Ford Ranger / B-Series :: Front Disk Pulsing - Brake Rotors?
My front disks are pulsing & the thickness is near minimum, so I guess I'll have to replace them soon. Is any particular brand better than others?
These stock ones are made by Bosch and I'm not impressed with their lack of resistance to warpage. I see "Drilled and Slotted" available at Rockauto. What's your experience? Are they any good?
Lexus LS 2007+ :: Gauge Needle Have Slight Pulsing Effect When Applying Brakes

I have a 1999 Subaru Impreza Wagon that I have owned for about 2.5 years, and I love it. I travel for work and I use rental cars alot. I have noticed in the past year that my brakes feel softer than most cars I drive, but I figure.. they are new cars, and my car is pretty old.
In the past 2-3 months I have notices a pulsing in my brakes...it sounds/feels kinda like the ABS, but I was thinking it would be worth getting my brakes inspected soon.
Then this past week, I totally blew a brake line when I was driving.
The car has about 140,000 miles on it and the mechanic says a brake line alone may not be related to the pulsing sounds...because brake lines usually go because of rust....
So...thoughts on things I should be looking at? What could the pulsing be a symptom of?
if one brake line blew, and it is rust, is the other one not far behind? (this was a new england car up until 2 years ago)
Ford F-150 - 1997-2003 :: Cruise Control - No Coasting When Put On Brakes Slightly To Slow Down
All, i have an issue ( or at least i think its an issue) with my 99 f150 5.4. When i use my cruise control, i notice when i put on the brakes slightly to slow down, it feels like its not coasting because you can feel the engine still engaged and wont coast. I think this happens even without the cruise on. What this could be? I have the latest update on the cruise control harness. I believe that was for power always to it even in off, causing fires.
View 3 RepliesFord - Excursion :: Slightly Warped Rotors But Shakes Without Braking
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.
View 5 RepliesPrius (2010-12) :: Pulsing Vibration In The Front Of Cab When Driving
My car is approx two years old. I bought it in the beginning of 2010. I rotated my tires about 10,000 miles ago after not rotating them for over 20,000 miles. initially the dealer said it was cupping on the tires but I have driven them since for close to 10k miles.
The same issue persists. Whenever I drive the car and it gets to around 30-40 mph accelerating or coasting I hear a very audible noise that almost sounds like pulsating vibration in the front of the cab. I've brought it to two different dealerships and they have both said it is the tire needing rebalanced but I somehow doubt that is the case.
Ford Excursion :: 2003 - Driveline Vibrations Mainly On Highway Speed And When Slightly Press On The Gas
I have posted several times about my 03 Ex and it's driveline vibes- mainly highway speed and when slightly on the gas... Took it to a local 4 wheel drive shop that specializes in lifts. They jacked it up and I ran the X up to highway speed with the rear in the air. It was amazing how rough it is, even at 55mph. I hardly feel it in the vehicle at that speed while driving.
Anyway, they felt the vibration but where it is coming from. They said pinion angle looked fine and since I have a retubed driveshaft and rebuilt rear, they ruled that out. The owner has an 04 with a 6 or 8" lift and 37's and seems to know about Excursions.
I then took it to the local Ford dealer and had the service manager drive it. He strongly feels it is gear mesh with the ring and pinion. I am not totally convinced as the rear is quiet, gear wise. For that matter, my slip yoke has quite a bit of torsional slop, likely as much as the backlash on the ring and pinion but the driveshaft shop said that it is acceptable.
Ford Excursion :: Transmission Output Shaft Play Slightly Up And Down - Torque Specification?
I removed my drift shaft to get balanced since I have felt a vibration at 55-60 mph. After removing the driveshaft I noticed there is some play in the output shaft when I grab a hold of the yoke on the transmission. The play is a slightly up and down. If my memory serves me right that should not be. Seal is not leaking but need diagram of this yoke off the output shaft. I know in past on other vehicles there is sometimes a crush washer. Also what is the torque specification for that output shaft nut?
View 3 RepliesFord :: 1997 - Front End Shakes Slightly When Braking With A/C On
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.
View 3 RepliesFord Aerostar :: Pulling Slightly To Right - Front End Alignment
Had upper control arm bushings replaced in June. Van has been pulling slightly to the right. Assumed it could be the tire since the front tires were due for replacement. Took it yesterday for two new tires and it still has slight pull to the right.
Here's the rub. The chain shop that did the work has since replaced their alignment machine and the new one does not have the specs for vehicles earlier than 2000. The machine also doesn't have the capability for manual input of the specs.
The manager has found a competitor that has an older machine and has arranged to pay for the alignment which I consider over the top. Evidently this is a trend we can expect to continue because in a city the size of Tampa, he could find only one shop with an alignment machine capable of alignment on an Aerostar.
