I have a pulsation in my brake pedal. It is very rapid at highway speeds. I just had new rotors and pads put on the front and yet the pulsation still exists. I can feel a slight pulsation just driving on the freeway even with my foot off of the brake pedal. I have 4 wheel disc brakes. I'm wondering if there is something that may need to be cleaned or replaced.

Hi there

This will be a rotor problem, if the steering shimmies under brakes its the front rotors and if only body & pedal its the rears.
