What Causes Squeaky Noise When Pressing Brake Pedal?
Squeaky noise when pressing the brake pedal can be caused by a variety of factors. Some of the most common causes include:
-
Worn-out brake pads: Over time, brake pads can wear down, causing the metal backing plate to rub against the brake rotor, resulting in a squeaking noise.
-
Warped brake rotors: Warped brake rotors can cause the brake pads to vibrate and make a squeaking noise when the brakes are applied.
-
Brake dust and debris: Brake dust and debris can accumulate on the brake pads and rotors, causing friction and leading to a squeaking noise.
-
Loose or worn-out brake hardware: Loose or worn-out brake hardware, such as the brake caliper or brake pad retaining clips, can cause the brake pads to move and make a squeaking noise.
-
Brake fluid issues: Low brake fluid levels, dirty brake fluid, or air in the brake lines can cause the brakes to malfunction and make a squeaking noise.
What Are the Symptoms of Squeaky Noise When Pressing Brake Pedal?
When it comes to diagnosing a squeaky noise when pressing the brake pedal, it’s essential to identify the symptoms. Some common symptoms include:
