How can I troubleshoot a faulty brake system in my Audi A5?

I recently noticed that my Audi A5's brake system is not performing as efficiently as it used to. The brakes feel soft and the car takes longer to come to a stop. What could be causing this issue and what steps can I take to fix it?

The most common cause of a soft brake pedal is air trapped in the brake lines. Bleeding the brakes, which involves removing the air from the brake system, can help resolve this issue. You can either do it yourself or take your car to a mechanic for this procedure.

Worn brake pads can also affect the performance of the brake system. These should be replaced every 30,000-70,000 miles, depending on your driving habits. Inspect your brake pads for wear and replace them if necessary to improve the braking performance of your car.

Another possible cause of faulty brakes is a leak in the brake lines. This can be identified by a decrease in brake fluid levels. If you notice any signs of a leak, it is important to have it repaired immediately by a professional mechanic to ensure your safety on the road.
