Accent MC (2006-11) :: Pulsating Brakes / Grab Momentarily When Stopped
May 10, 2012
I started noticing that the brakes would pulsate, or grab momentarily when almost stopped. I figured that the rotors might be warped, and as I was planning on putting on new green stuff pads and rotors I was waiting for a convenient time to change them.
Now I have noticed some type of fluid, I'm guessing grease, on the side of one spoke of one of the wheels. I recently replaced the steel wheels with SE 16" wheels. I didn't see any leaks then but I guess I wasn't looking like I should have been.
I'm trying to decide what I should be looking for. CV boot leak? Front wheel bearing seal? Brake fluid?

I'm getting this checked today most likely as it's been happening for months now. No issues with vibration and stopping is fine. As a matter of fact brakes are excellent. However when I'm stopped at a light or whatnot and I depress the brake pedal there's a pulsation that occurs almost every time. It's fairly constant and only happens when I'm at a stop not when I'm stopping so I know it's not a warped rotor. What it might be?

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.

I recently got new brake pads put on (front and back) and while they work ok there is no grab in the brakes like there used to be when they were new. They are quieter than the old ones. Do they have to break-in? Should I have gotten the rotors replaced too?

I have an ABS light that likes to come on and off. My rear tires lock up when I come to a stop. Stopping sometimes takes longer distances. Other times I can barely touch the brakes and they'll grab real fast and then become soft immediately. Every time I hit the brakes is different I never know what to expect. There's usually a real long Rea of play in the pedal. As in I push it about half way down then the brakes with grab. Other times I barely put my foot on it and it jerks the truck but then loosens back up and comes to a (normal for the truck) stop. What could this be? 1997 4.6 4x4 f150

2004 Canyon, rear brakes squeal and grab, and occasionally stick. I know its the semi-metallic rear shoes, is there a cure for this condition?

My 98 Sunfire has a grab and release feel when applying brakes. Mechanic fixed this same problem March 2012. I was told it was warped rotors and brake pads. This worked great until four weeks ago when it started again. I find it hard to believe that rotors and pads would warp again after 7 months. Also the front brakes lock up real easy on wet surface such as a light rain. When they lock up I get a bad rattle sound under the dash. ABS light does not come on and never has. This happens all the time. Even after new pads and rotors were installed.

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.

2000 Chevrolet Silverado 1500... When slowing down for stop, when almost stopped, sometimes the brake pedal pushes back momentarily, makes a bit of a (errrr) noise, and for two or three seconds during the push back the brakes do not work. Mechanic has cleaned ABS wheel sensors. All brake pads are good. The truck computer shows all systems okay. All brake lines are new or one year old.

A few weeks ago on a short drive, my car (2000 Toyota Corolla) started shuddering/pulsating when I was stopped at a red light (and it kept doing that intermittently as I drove the few blocks home.) Next time I tried to start it, it turned over but then died. Towed it to the mechanic, he said it was a dead ignition coil, he replaced the coil and it was able to start again.
Less than a week (and not much driving - 50 miles tops) later, on the highway, it starts shuddering again, feels way underpowered, and the check engine flashes. It's pretty scary. I pull over and have it towed to the mechanic. (It still starts up but doesn't feel safe to drive, plus the check engine light is flashing.) First he says one of the fuel injectors needs to be replaced, then he says that on further testing it was actually another dead ignition coil. He replaces the ignition coil (he didn't end up replacing the fuel injector) and I pick up the car.
It's fine on the drive home (which is about 3 city miles, no highway driving) and on another neighborhood errand, and the check engine light isn't on, but now it's sort of shuddering again. I don't want to keep driving it and/or try it on the highway to wait for it to get worse.
I guess I'll take it in again tomorrow, but does this seem odd at all? I know some people replace all 4 ignition coils at once pre-emptively, but it would seem strange for 3 to fail within ~150 miles (assuming this is yet another ignition coil.) What else might be going on? I had the spark plugs changed last year so those should be fine. The car has pretty low miles on it (about 100k) for the age.

I have a 2008 T Spirit 3 with 100k on the clock which runs perfectly fine apart from one niggly issue.
Sometimes when I brake and the speed is below 7mph it feels like the brakes have failed momentarily and the vsc light will flash and then the brakes will clamp on again.
It happens at least 20% of the time when I brake. Why this is?

I just had new rear drums put on, my front brake pads are new, my rotors are good...but there is still a pulsating when I brake. When I am just about slowed down you can definitely feel a surging coming from somewhere. The steering wheel does not shake, and I don't feel more than a vibration from the brake pedal. I have taken it to 3 mechanics and replacing the drums was given as a solution. But since I have already done that, the problem is obviously not resolved. I know I need new tires as 2 of them are really cupped and loud...could that be it?

Got new brakes 4 months ago - except this time put in redstuff ceramic pads.
I've had really bad vibration and grinding lately so I just had the rotors machined and cleaned up.
Some of the vibration is gone but when I apply the brakes more than very lightly I get shaking shuddering including the steering wheel. If I apply the brakes harder it goes away.
I would estimate the pulsating/shuddering/shaking happens when I apply the brakes more than 10 percent up to say 40-50 percent. Very light pressure no problems and hard braking no issues.
This has gotten worse since the servicing. What could be causing this? I've already replaced the propshaft and am replacing the tires.

My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.
I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".
Its a 2012 Elantra Limited, all stock everything, 53981 miles.

I don't use my car much, and park it on the street. I last drove it 3 weeks ago, and it did great on a 6 hour trip. It is worth noting that until this year, the car had lived in Washington, and this 6 hour trip was the first welt salted road experience the car has ever had.
Today, I go to drive it, and the first time I hit the brakes, I'm greeted by the entire car shaking and the brake pedal pulsating. My first thought was "wow, are the roads really that icy? that's a lot of ABS...". I then realized this was absurd, the roads are clearly dry and this doesn't quite feel like ABS (although it's a very similar feeling at high speeds). My next thought was that I must have ice in the pads, it'll melt off soon. So I drove 20 minutes, and it didn't improve. I turned around, and drove home.
When I first moved the car, I had to give it gas to get it to go and heard a snap. I assume this was it being stuck in ice as I hadn't driven for a while and it was very cold. It could have been something breaking, though.
I have since taken off all the wheels, visually inspected the drum brakes for any damage (pads look fine). I looked at the disc brakes and they looked fine. One of the caliper slide pins was completely seized, so I was hoping that'd fix it, but it had no effect at all.
The brake fluid level is full. I seriously doubt this is warped discs, because it drove perfect last time I used it and it was spontaneously so bad today.

I have a 1999 C2500 Chevy Silverado extended cab. On some slow speed stops the ABS kicks in and makes it hard to come to a full stop scary. There are no leaks in the system. The ABS light has come on, on the dash off and on. I thought I saw a post that you can shut off the ABS system not the real fix but safer until I can figure it out.

I was in the RX450h with my son, everything's fine, its running smooth like a purring cat. I get to the bottom of the hill at a traffic light and stop with my foot on the brake.
Then it just started pulsating, engine comes on, goes off, comes on again, goes off - almost like a pressure washer with an internal leak
It went away after 30 s or so and hasn't come back. No engine lights or hybrid system warnings.

2003 Hyundai Accent. I will try to give a good description of the issue. Wheel was shaking (or was noticeable) at about 60 mph. Lessened after that but still bad. I had my tires changed and balanced as well as an alignment. My rear right toe is still off a bit. Now, the shaking is noticeable at 68-70 mph and higher. Pedal shakes, wheel shakes. I can feel some vibration all over including the seat, gas pedal and wheel the most. Wheel not jerking, just vibrating mildly.
It is not quite as bad as before and does not happen until 68-70, 10 mph higher than before the tire change/balance. I have put my back wheels on the front and it is the exact same condition - this would remove tire and balance as the culprit (?). I also hear an audible hum.. kind of a pulsing sound at 50 mph+. This speeds up and slows down with my speed. For instance if I am going 70.. I hear it every half second, 50 mph I hear it less often. It is pretty faint, not a thump. It seems to be coming from the front but I can't pin-point it. I feel no tire play up/down/side/side.
What is the next step here? I'm going to get the rear toe fixed but this shouldn't be the cause of the pulse/wheel + pedal vibration. Vibration/sound doesn't happen when I am braking. No rubbing shield behind rotor.

So I've been driving my tiggy with the rusted brakes from when I left it for a few months during this past winter season outdoors. I had VW check on it and they said that the only way to fix the problem is to replace the brakes (rotors and pads, I assume) for over $1k. Is there really no way to maybe scrape/sand the rusts out? Right now, when I step on the brakes, I have the pulsating feel and the car shakes when coming from a high speed. At first I thought it would go away after driving it a bit and stepping on the brakes since I did just that last year when I left it for a month during the winter season as well. If the only way is to have the brakes replaced, then I guess I have to shell out the money.

So I had all of my belts changed including timing belt and tensioner pulley as well as an oil change. After, I noticed a weird pulsating grinding/wining noise coming from the engine bay. It only can be heard once the car is warmed up. (It is much louder in real life.).

My wife recently bought an automatic 2007 Accent. And I'm in charge of fixing some issues, then of course eventually upgrading some parts.
Now here's the first issue. I notice this strange sound like something is loose and rattling coming from the driver side not sure if it's from the inside or under the hood.
Only happens when the car is stopped, brake pressed, and in Drive. Put the car in reverse, park, neutral, no sound. Also no sound when in D but only when the handbrake is engaged and the brake pedal is depressed.
The car runs smooth, tranny shifts good, sluggish acceleration though. I drive a 2.4L turbo car so maybe this is just normal for the 1.6 Accent.
