Check that the booster has not developed a vacuum leak, test by undoing the booster vacuum line and blocking, apply brakes, if shake is gone replace booster, (do not do this as a drive test, with the booster disconnected you will have very heavy and poor preforming brakes)

Hi guys. I think there might be some confusion here. WHAT shakes, the engine or the brake pedal / whole car? Does the shaking occur when the car is standing still or just when you're stopping the car?
