The first thing you need to know is: When was the last time thebrakes were changed? If you just bought the car, this is somethingto ask the dealer or whoever you bought it from. Most carsshouldn’t need a brake change more than every 40,000 miles or so.If the car has done a lot of in-town driving (lots of stopping),then it might need a change sooner. Another way to tell is if thebrakes are making a noise, but this isn’t the most accurate gauge.Most modern brake systems have an early warning device built in tosqueal when the brake pads are wearing thing, but sometimes dustand dirt can build up in the tires and cause the brakes to squealas well. The only sure way to tell if a brake needs changed is totake the tire off and look at the brake pads. To change yourbreaks, follow these steps.- This
