Why Do My Brakes Make Noise?

1. Brake Pads: When brake pads wear down, a squealing or scraping noise is caused from
the metal to metal contact. This is a sign that you need to replace the brake pads.
2.Brake Rotor: A brake rotor, or brake disc, is a flat, circular metal disc that is mounted
directly to the wheel hub or axle. When the driver applies the brakes, the brake pads are
squeezed against the brake rotor, causing the vehicle to slow down or stop. Worn, warped,
or uneven brake rotors can cause vibrations and noises when the brake pads contact then.
Excessively warped or thin rotors should be replaced.
3. Contaminated Brake Pads: Things such as dirt, debris, or moisture on the brake pads can
lead to noise. Keep the brake system clean.
4.Weather: Extreme temperatures of hot or cold, can cause expansion or contraction of the
rotor, that will result in noise.
While these are the common reasons, Brake noises of any kind can be a sign of an issue
worth checking out. If you hear any sounds, have a qualified mechanic inspect your vehicle.
Regular maintenance, proper installation and timely repairs will ensure safe and quiet
