The most common reason brakes squeak is that they are worn out. The squeak is the sound of the metal wear indicator on the brake pad coming in contact with the metal rotor. Your brakes are the top safety feature on your vehicle, so come by 625 Auto Repair and get them replaced right away. If you hear a squeaking only when you press the brake pedal the first 2-3 times when you first start driving in the morning it is the result of overnight moisture build up and likely nothing to worry about.
