A little brake squeak can make you wonder if something is about to fail or if it is just an annoyance. Some noises are harmless side effects of how modern brakes are built, while others are early warnings that the pads, hardware, or rotors need attention. Learning how to tell the difference can save you from guessing and from waiting too long on a real problem. Why Brakes Start to Squeak in the First Place Brake pads create friction against the rotors, and that friction can easily turn into sound. When the pad surface and rotor vibrate at certain frequencies, you hear that as a squeak or chirp. Moisture, light surface rust, and even the type of pad material all play a role. As parts wear, clearances change, and hardware loosens slightly, which can give those vibrations more room to develop. That is why a brake system that was quiet for years can start to sing or chirp as the miles add up, even if the car still stops well. Normal Brake Noises You Can Expect ... read more
