ABS, ANTI LOCK BRAKING, only works when the senors located on the hub detect a wheel locking up, when the wheel locks up the ABS pump kicks in, the effect is like cadence braking in the old days when you would pump the brake pedal so you could still steer your way out of trouble, ABS would not operate under heavy braking if the wheels did not lock up. Under normal braking conditions the ABS will have no effect.
