How do I know when to change my Nissan Micra's brake pads?

I have been driving my Nissan Micra for over 3 years and I'm not sure when or how to tell when my brake pads need replacing. Any tips or advice?

Emily, it's important to regularly check your brake pads for wear and tear. A good rule of thumb is to check them every 5,000 miles or every 6 months, whichever comes first.

Hi Emily, a tell-tale sign that your brake pads need to be replaced is if you hear a screeching or grinding noise when you apply the brakes. Don't wait until it's too late, get them checked by a mechanic as soon as possible.
