If you've been hearing a faint screeching or squealing noise from the front of your 07-11 Toyota Camry while braking, you may need to replace the front brake pads. They usually last anywhere from 40,000 to 70,000 miles depending on your driving conditions and personal style.
A set of new aftermarket pads range in price from about $35 to over $70. I'd recommend buying a set of ceramic pads which emit less brake dust, are quieter and stop better.
