Why is my Audi A4's steering wheel vibrating while braking?

I have noticed that whenever I apply the brakes in my Audi A4, the steering wheel starts to vibrate. This only happens when I am driving at higher speeds. Any idea what could be causing this?

It is possible that your brake rotors are warped or uneven, causing the vibration when the brake pads make contact with them. This is a common issue in older cars or those with high mileage.

Another possible cause could be worn out brake pads. When they start to wear down, they can cause an uneven braking sensation and vibration in the steering wheel. It may be time for a brake pad replacement.
