Same problem for me, just had rotors resurfaced. No more problem, and this was after about 75,000 miles.
replaced rotors and took away the pulsing had to purschase higher grade pads to reduce how quickly the brakes needed to be changed
had to have the brakes changed many times
Rotors appeared like a record - lines around the rotor that could be felt and seen. New brake pads lessened the vibrations during stopping, caused by maintenance neglect by a previous owner.
I have owned my Chevy Malibu since 2012 and I have had to get my front brakes and rotors changed several times due to the problem of my front end rattle when I press on the brakes.
Strong front brake vibration shaking the steering wheel back and fourth due to warped brake rotors. Front brakes wear out at 30,000 mile intervals. Rear brakes do not wear and do not work except when used during parking. Front brake rotors still warp at 30,000 miles when using ceramic brake pads. However, the ceramic brake pads are only worn 25-percent with 75-percent thickness remaining. GM appears to be using undersize brakes on the front axle while the rear brakes may only apply stopping effort at or near lockup brake pressure.
I had replaced my rotors at about 35,000 miles. Around 50,000 + or even earlier I started to feel a pulsing in the brake pedal. The rotors looked ok, but I did not check them for run out. At about 60,000 it got very bad and I replaced the rotors with Bendix rotors and replaced the brake pads. Now braking is smooth.
have had the front brakes done a few times. A year ago the rotors resurfaced and now it is pulsating again when braking.
