Question about 2003 Buick Century

2 Answers

Pulsating brakes I have a 2003 Buick Century with 143000 miles on it. My front brakes pulsate when i step on them. You can usually feel it more as you go faster and step on the brakes. It drives fine down the road until I press the brake. I've had the brakes and rotors replaced twice. Once under warranty. The pulsating is still there when i step on the brake pedal. What would make it pulsate after the brakes and rotors have been changed.

SOURCE: I have a 1996 buick century with little brake pedal resistance

not sure here,firstly remove rear brakes and clean lip out on drum then manually adjust rear brakes,if still no pressure then renew master cylinder,tandem master cylinder and if seal between front and rear chamber is worn you will never get any pressure just brake pedal creeping away to floor

SOURCE: Strong Shutter or Pulsation when applying brakes

Have you checked the rear brakes? They can cause shaking just like the front can.

I recently put new front brake pads and had rotors turned on the front end of my 2003 tundra sr5,after a month of driving i'm getting the pulsation when braking back which is why i made this repai


HI if you have pulsation after a month you must replace the rotors
they are too thin and the heat is warping them faster then before you
had them turned
note you replace brake pads and rotors

good luck

ABS, TRAC OFF, SERVICE VEHICLE SOON LIGHTS ARE ON. BRAKE PEDAL PULSATES INTERMITTENLY AND MAKES NOISE.


with these lights on then you will have to see what codes are in the abs and pcm module to find out what the problems are.the abs module will activate when the traction control lights come on.this can also cause a noise and pulsate in the brakes pedal.

The pulsation is normal and caused by the antilock brake system, any time the brakes are applied rapidly the abs will kick in and you will feel pulsations in the pedal.

HAVE A "GROWLING" SOUND FROM THE FRONT LEFT WHEEL, BREAKS ARE PULSATING. WHAT COULD BE THE PROBLEM


the brake pads are worn to nothing so you have a metal to metal contact making that noise. the brake rotor will be considered junk as well since it is very noisy

The pulsating can be one of 2 problems, they feel very different, unfortunately, I can not feel what you feel, so here goes. One problem could be with your abs system, possibly diagnosed with an OBD II reader, the other could be warped rotors, but not likely since you replaced. Good Luck! I hope you find this to be very helpful!

You can do a quick check yourself to see if the back rotors are warped. Warping is the most common cause of your problem and normally is the front rotors, but not necessarily the only one. All you have to do is block the front wheels of the car and jack up the rear one side at a time. With the wheel clear of the ground, turn it by hand for a few turns. If the rotor is warped you should feel some extra drag at some point when you are turning the wheel. Do both wheels and double check the front. I have seen new rotors that had to be turned because they weren't straight.
If you don't feel anything I would be inclined to look at the ABS because it can create a pulsation when it is working. Hope this helps.

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.
