Anti-blocking system of brakes

The anti-blocking system (ABS) always provides optimum pulsing, that is faltering braking so full blocking of wheels when braking the car which is equipped with this system is impossible. Even at full braking on smooth ice of a wheel still slightly rotate in order that did not take away the car aside.

ABS is not a panacea!

ABS cannot make any miracles when braking as drivers often think; so considerable reduction of a brake way happens not under all conditions.

ABS helps to keep controllability the car during strong braking more likely. But for this purpose the much bigger turn of the operated wheels, than usually is necessary for system. It is only one of points distinguishing ABS from the normal brake system:

  • Practice on the empty spacious parking in performance of full braking at big turn of the operated wheels.
  • At the same time completely squeeze out a brake pedal. Dispensing of brake force – a problem of ABS, but not yours.
  • It is right for braking both at the rectilinear movement, and at the turned-out operated wheels (turn).
  • Be not surprised concerning the pulsing brake pedal. When ABS works, it fluctuations of a pedal are absolutely normal.
  • In extreme cases you should take away a leg from a brake even the car equipped with ABS that without problems to get out of the dangerous situations on turn.
