Understanding Brake Pedal Squeaks: Causes and Symptoms
A brake pedal squeak can be caused by a variety of factors, ranging from worn-out brake pads to misaligned brake calipers. To diagnose the issue, it’s essential to understand the symptoms and possible causes. Here are some common reasons why your brake pedal might be squeaking:
- Worn-out Brake Pads: Over time, brake pads wear down, causing the metal backing plate to rub against the brake rotor, resulting in a squeaking sound.
- Misaligned Brake Calipers: If the brake calipers are not properly aligned, they can cause the brake pads to vibrate, leading to a squeaking noise.
- Brake Rotor Warpage: A warped brake rotor can cause the brake pads to vibrate, resulting in a squeaking sound.
- Loose or Worn-out Brake Hardware: Loose or worn-out brake hardware, such as brake springs or clips, can cause the brake pads to move excessively, leading to a squeaking noise.
- Brake Fluid Leaks: A brake fluid leak can cause the brake system to malfunction, leading to a squeaking sound.
Common Symptoms of a Squeaking Brake Pedal
When your brake pedal squeaks, you may notice the following symptoms:
- High-pitched Squeaking Sound: A high-pitched squeaking sound when you press the brake pedal.
