How do I know when it's time to replace my Audi A1 brake pads?

I've noticed that my Audi A1's braking has become less responsive and there is a grinding noise when I press on the brakes. What could be causing this and how do I know when it's time to replace my brake pads?

It sounds like your brake pads may be worn out. This can happen due to normal wear and tear or if you frequently drive in stop-and-go traffic. To be sure, you can inspect your brake pads by looking through the wheel spokes. If they are less than 1/4 inch thick, it's time to replace them.

In addition to the symptoms you mentioned, a pulsing sensation in the brake pedal or steering wheel could also indicate worn out brake pads. As for when to replace them, it's recommended to do so every 50,000 miles. However, if you frequently drive in city traffic or have a heavy foot on the brakes, you may need to replace them more often.

As for replacing the brake pads, it's best to have a professional mechanic do the job. This ensures that the pads are installed correctly and that the brake system is properly bled. However, if you have experience with car maintenance, you can also opt to do it yourself. Just be sure to follow the manufacturer's instructions and use high quality replacement pads.
