View 10 RepliesMy '07 shakes when braking below 7 mph. Coming to a complete stop is never perfectly smooth unless medium to hard braking is required. My thought was that the MG2 is in creep mode even while my foot is lightly on the brake pedal, causing the jerking, but creep works properly while not braking.
The shaking is very steady, at about 6 Hz, the same frequency as the "popping" noise one hears when stopped at the light with the foot lightly on the brake; just enough to keep the car from creeping, but not mashed far enough to turn off the creep current from the battery. I take it there's two sensors on the pedal as well as a potentiometer. Could the problem be mitigated if the creep current were cut off at the presence of a foot rather than having to press harder? There is no shaking on a harder stop, only the slow ones.
Another thought I had was that the pressure pump itself is supplying the brake pressure to the friction pads, causing the pulsing. In a previous thread, we discussed why my pump was coming on so often. Perhaps a leak in the canister causing the pressure not to be buffered, and the pump itself providing the pressure.

I went to go get a wheel alignment (when driving my car starts drifting to the left hard/ also when my hands aren't on wheel) and they discovered that my front left tie rod is wobbly (also said lower ball joint is suspect). I was told they couldn't perform a complete wheel alignment until fixing the front left tie rod first.

The front end of my car shakes (sometimes, more often than not, but not always) while braking. It doesn't matter if I am braking hard or regular. I do not feel it while accelerating or cruising.
So, my thinking is rotors and pads wearing unevenly, warped, or something along these lines. I plan to pull the rotors off and look at them this evening.
I am just looking at if there are any other opinions or options that I should be checking into to cause this type of thing to happen.
The whole front suspension was replaced a couple months ago, so all should be well there but will look it over while I have the wheels off.
I have a 95 940 turbo that shakes really bad when braking. things I have done so far are.
1. Replaced all four rotors.
2. Replaced all four callipers.
3. Replaced sway bar control arms.
The shaking is so bad that the gear shift moves back and forth when braking.
Taking my car to get the brakes serviced this week. Every time I brake at a high speed the car shakes. I am guessing best case scenario I get the rotors resurfaced and worse case new rotors.
View 9 RepliesI just recently got a 2004 r32 and it came with almost brand new rotors/pads, at most 500 miles on them. I just realized the other day that when driving freeway speeds, about 70-80 and braking down to 40-50 the entire cabin shakes.
View 24 RepliesI 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 RepliesMy 06 sonata's steering wheel recently started shaking when I am braking from speeds of 80+ also a little when going down really steep hills. This happened once before when I got new front tires because the tire shop didn't balance the tires correctly. I know it could also mean warped rotors but in my experience rotors only become warped when you drive them with really low pads. Btw the car has 46k miles on it, and it is a 3.3 liter v6 gls.
View 9 Replies2001 Hyundai Sante Fe. When braking, I get a noise and the whole vehicle shakes. Exactly as if I were driving in snow and just slammed the brakes. The feeling & noise feels and sounds the exact same as if I were sliding...
I've replaced the master cyl originally just because today is the first day the issue lasted long enough for me to fully hear//feel the whole issue. It's normally brief.
My T&C strikes again... Now it shakes when braking at highway speeds (thinking rotors are warped and need changed), but today the brake light, traction control, and ABS lights all come on and stay on when I drive...
View 4 RepliesI have an 05 Camry LE & when ever I'm on the highway going around 50-80mph & need to break my steering wheel starts to shake until I either stop or put my foot back on the gas. Last year my power steering rack & one of my motor mounts got replaced, & for awhile it stopped & figured because that was going out that's what was causing it.
Well about a month later it started back up & still does it, I've taken it to the dealership & have told them & they test drove it, felt the same thing I felt but didn't find anything. Is there anything else that could be causing it ? Earlier last year my bearings were lose in the front, and I managed to get my brakes stuck & had that all fixed & since then that's when it started shaking . I took it back to that shop & mention every time I go in for oil changes at my dealership, is there something else I'm not aware about that I should ask them to look at ?
So. My car shakes badly when I get above 35 mph and up. It shakes under acceleration and braking above these speeds. Under these speeds its fine. When I am above 35 if I am just coasting its fine it doesn't shake. The shaking feels like I am off the side of the road and driving over rumble strips. What could be the cause of this?
View 19 RepliesRecently 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 RepliesI have a 2001 vw Jetta with a manual transmission (just over 155,000 miles). My first set of front brakes lasted to about 135,000. After they were replaced a shimmy started to appear when braking a few thousand miles in. At about 8,000 miles the shimmy became so bad that I brought the car back to the dealer. They said the rotors were warped. The pads and rotors were replaced again and in about 5,000 miles same thing. The pads and rotors were replaced again at no charge and it is now about 5,000 miles later and the same thing is happening again.
View 2 RepliesMy 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.
View 14 RepliesI just bought a 2009 Toyota Camry with 78K miles on it. Everything is great except at highway speeds it shakes and vibrates when braking. The higher the speed the worse it is. Steering wheel shakes as well. I pulled both front tires off and the rotors appear to be smoothe on both sides with no grooves, etc. However, I'm due for new front brake pads. There's some pad left but could that be why it shakes and vibrates when braking? How do you tell if rotors are warped? Rotors are smooth but could they still be warped?
View 16 RepliesI've been noticing my steering wheel shakes if i normally brake going on the highway at high speed. My friend said that it's probably your brakes and rotors. Get them replaced and resurface and that should fix the problem. Can i get some confirmation before i do this?
1. I just had my tires replace at 55k and bought this car new back in feb 09. it has 62k.
2. also i've been reading up on camries fail water pump. i'm thinking of doing this over the weekend or should i just wait until i notice some leaks?
3. lastly, any major thing i need to be aware of. i've done the normal engine oil and filter change, cabin and engine air filter change, that's about it. i hope these camries are bullet proof like the old school (92-95).
I have 2003 F150 SuperCrew 5.4L XLT. For past month or so, have been hearing metal rubbing sound and had shakes in braking - as well as a "grabbing and pulling" sound near brake pedal - very aggravating to say the least. Weird thing is the grabbing and pulling sound only happens under 10 miles an hour or coming to a complete stop. (The grabbing sort of sounds like the sound the ABS makes when hit really hard)
Yesterday I had brakes and rotors replaced - mechanic said front rotors were beyond turning - very bad. 135,000 miles on truck. Felt more comfortable until I pulled out of shop and when I applied brakes, had the same grabbing/grinding sound, but no pulling. Went back to mechanic and had him ride with me to hear sound, and he is stumped.
Knew it was safe(r) to drive since new pads/rotors installed, but when I got up to 55mph and barely touched the brakes, the steering wheel began to shake violently - but no sound/grabbing from brake pedal area like I get when I am 10mph or under. Really at a loss right now.. What's going on?
Truck is a 2WD, also hear some thump thump thump sounds from front left tire, which are only one year old, but tire man said that was from suspension arm or something - nothing to worry about he says.
Some people have said "bearing" or "hub" but when brakes were replaced, the bearings were repacked...is this the same thing? Is the current problem safe to drive with? I do not take vehicle out of the county - just to work and back and hunting on weekends.
What could cause this? Its coming from the rear end. It seems to happen if I am going over 45mph and apply the brakes. It feels like a warped rotor, but if braking from 40mph and below, it is smooth. Both rear wheel bearings have been replaced. Tires are new. There was a vibration while cruising between 40&50mph, which was "cured" by the new tires... While replacing the wheel bearing, I noticed some play in the right rear axle at the joint closest to the wheel.
View 11 Replies05 GX 470...no KDDS...100k miles. When I've been driving a few miles, I feel a pulsating when braking. Feels like it's coming from the front (front left if I had to guess). I put in new rotors and brakes in the front, turned the back rotors and problem still persists, no improvement.
I'm now considering the hub-bearing. However, when I do the standard-check (lift wheel and apply stress from top/bottom) there's no indication of a bad hub bearing.
The problem worsens as I drive faster. When on the highway, if I start to turn the wheel right 'then' brake...the steering wheel pulsates bad. When I turn the wheel left 'then' brake, it's not as bad...but still noticeable. When I start pressing the brake pedal 'then' start to turn the wheel right it's still there but not as bad compared to applying the brake after turning.
There's no pulsation in the break pedal, only the steering wheel and body/chassis.
