Unusual noises when apply the brakes
When you apply the brake pedal you will notice a screeching or scraping noise. This is noticeable immediately and is a sign that the brake discs are worn, warped or damaged.

You may notice that it takes longer for the vehicle to come to a stop. When the brake pedal is applied you might feel vibrations through the pedal, if you continue to drive and the condition worsens this can prevent the pedal from interacting with the brake disc completely preventing the vehicle from stopping completely.
Any damage or wear to a brake disc can cause you to feel vibrations throughout the car and not just the brake pedal. As soon as you notice any out of ordinary vibrations you should book your vehicle in for a brake inspection.
