ABS and EDS

In drawing the basic design of system of antiblocking in Audi A4 is shown.

ABS cannot create a braking miracle as it often is supposed; a brake way it becomes essential more shortly not under all conditions.

In a greater degree ABS helps to keep controllability the car at strong braking. But for this purpose much stronger turn of a wheel, than usually is required. It only one of the moments, other that at usual brake system:

  • Therefore be trained on the remote parking platform to full braking with wheel turn.
  • Thus completely wring out a brake pedal. A dosage of brake effort for you incurs ABS.
  • It concerns braking at movement both on a straight line, and at wheel turn.
  • Be not surprised pulsations of a pedal of a brake. When ABS regulates braking, this vibration of a pedal is the normal phenomenon.
  • In extreme cases even in the presence of ABS you should release a brake pedal to rescue a ticklish situation turn.
