The figure shows the basic structure of the anti-lock system in the Audi A4.
ABS cannot create a braking miracle, as is often assumed; the braking distance becomes significantly shorter not under all conditions.
To a greater extent, ABS helps to maintain control of the car under heavy braking. But this requires a much stronger turn of the steering wheel than usual. This is only one of the points, the rest are those with a conventional braking system:
- Therefore, practice in a remote parking area full braking with a turn of the steering wheel.
- While doing this, fully depress the brake pedal. ABS takes over the dosage of braking force for you.
- This applies to braking when driving both in a straight line and when turning the steering wheel.
- Do not be surprised by the pulsation of the brake pedal. When ABS regulates braking, this pedal vibration is normal.
- In extreme cases, even with ABS, you must release the brake pedal to save the sticky situation by turning.
What does ABS do?
ABS always provides optimal «intermittent braking», so pure blocking braking is no longer possible. The wheels on smooth ice, even with full braking, still rotate a little in order to keep the car in a rut.
