Problem Description and Possible Solution
Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians often recommend replacement of the front rotors and brake pads as the best option to correct this condition.

Same problem for me, just had rotors resurfaced. No more problem, and this was after about 75,000 miles.
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.
