ezt en sem ertettem, egyik kommentelo megmagyarazza:
Gs from cornering shift the pistons and pads in the caliper, creating a gap. When the pedal is pressed there will be play in the pedal due to that extra gap (pedal drop). This results in the brakes not engaging fully, which could cost you the corner, or your car. So by tapping the brake pedal he is simply re-setting the pistons so they give a nice solid pedal feel, and full brake response. hope this helps!
