Pulsating brakes and peddle pushing back up


This is a classic ABS problem. Either the pump or the ABS controller. But as it is causing the brake pedal to push back you should get it seen by a qualified mechanic and DON'T drive it until it is fixed.

Replaced the right front wheel bearing after pulling the old one it was bad, Tire store said it was not the tires that was causing the virbration, replaced pads and rotors now the virbration feels like...


Could be the inner cup of the cv shaft or the carrier bearing if your vehicle has a halfshaft before the cv axle. If your getting pedal pulsation it must be a bad rotor. Now it should only do it when brakes are applied. Ive seen cases where the pads are very new and the rotor is so warped it will pulsate abd vibrate even withouth applying brakes. Other possobilty is that spindle was damaged and warped/ bent while pressing in new hub bearing.

I have a 2004 alero and when I press on the brakes to stop at a red light or stop sign a vibration occurs and it's loud but when I put it in park it stops vibrating. What can I do about this problem?


Sounds like you have warped rotors and or a lose caliper mounting bolt . When you stop do you feel a vibration in the brake peddle or in the steering wheel or both ? IF you feel the pulsation in the brake peddle I would suspect a brake pad / brake rotor problem . Now if you do not feel it in either and the vibration is through the whole car with out the brakes being applied i would think it may be related to and engine/drive line problem (motor mount /trans mount /axle problem)

I just bought a 96 lasabre and it wobbles, the previous ower said something about it being caused by the brakes or rotors, please help


if you get a pulsation/vibration when you apply the brakes than the brake rotors are warped. If the pulsation/vibration can be felt as your driving without applying the brakes than some common causes could be a tire out of balance, a separated tire, or a bent wheel,

Brakes pulsating


Hi,

If you have ABS on this vehicle which these models do, the brakes will ulsate if the pedal is depressed quite hard.

It does this because the ABS is working and it does make the brake pedal feel like its vibrating.

Hope this helps

Thanks

2004 impala vibration when pressing brakes


hi sounds like a brake pulsation remove the brake rotors and make sure the hub face is clean of rust and the inside of the rotor reassemble the brakes and torque the wheel nuts to 100ft/lbs if it still pulsates then the rotor is warped some aftermarket rotors are warped from sitting on the shelf you can also check the laterial run out of the rotor with a dial indicator if you have one hope this helps
