What Causes Brake Squeaking or Squealing, and How Can We Fix It?

Are you tired of the annoying squeaking or squealing sound every time you apply the brakes in your vehicle? Brake noise can be quite unsettling, but don't worry, you're not alone. Many drivers experience this issue, and fortunately, there are solutions. In this comprehensive guide, we'll delve into the various causes of brake squeaking or squealing and provide you with expert advice on how to fix it. At S&S Bavarian Auto, located in the beautiful city of Chattanooga, TN, we have years of experience in diagnosing and resolving brake issues, ensuring your safety on the road.

Common Causes of Brake Squeaking or Squealing

Brake Pad Wear: One of the primary culprits behind brake noise is worn-out brake pads. Brake pads are designed to gradually wear down over time, and when they become too thin, a small metal indicator will make contact with the rotor, creating a high-pitched squeal. Regular brake pad inspection is crucial to catching this issue before it escalates.

Dust and Debris: Accumulation of dust, debris, or road grime between the brake pads and rotors can cause friction and result in a squeaking noise. This issue is particularly common in regions with a high amount of road dust or where construction is prevalent.

Glazing: Brake glazing occurs when the brake pads become overheated, causing the friction material to harden and create a shiny glaze on the surface. Glazed brake pads can lead to noise and reduced stopping power. Aggressive braking or riding the brakes excessively can contribute to this problem.

Uneven Rotor Surface: Over time, the brake rotor can develop irregularities on its surface, such as grooves or deposits, due to prolonged use or harsh driving conditions. When the brake pads come in contact with these imperfections, it can cause squeaking or squealing sounds.

Moisture and Corrosion: Moisture and corrosion can form on the braking system components, especially during periods of inactivity or exposure to humid environments. The presence of moisture can lead to a temporary squeaking sound until the brakes warm up and dry out.

Brake Caliper Issues: Faulty brake calipers can also contribute to brake noise. Sticking caliper pistons or uneven brake pad contact can cause abnormal wear, resulting in noise and reduced braking performance.
