Human: How do I know if I need new brakes on my car? Assistant: 
You can check the condition of your brakes by using a brake inspection light or feel the brakes to see if they are making any abnormal noises. Additionally, you may want to take your car for a test drive and observe how quickly it stops when you press the brakes. If you notice that the car is not stopping as quickly as it should, then you likely need new brakes.
