What Causes Brake Screeching?
Brake screeching is a symptom of a problem with your car’s braking system, and it’s often caused by worn-out or damaged brake components. Here are some of the most common causes of brake screeching:
| Causes of Brake Screeching | Description |
|---|---|
| Worn-out Brake Pads | Brake pads are designed to wear down over time, and when they become too thin, they can cause the brake caliper to rub against the rotor, resulting in a screeching sound. |
| Warped Rotors | Warped rotors can cause the brake pads to vibrate and rub against the rotor, leading to a screeching sound. |
| Brake Caliper Problems | Faulty brake calipers can cause the brake pads to stick, leading to a screeching sound when you press the brake pedal. |
| Brake Fluid Issues | Low brake fluid levels or contaminated brake fluid can cause the brakes to malfunction, leading to a screeching sound. |
| Loose or Worn-out Brake Hardware | Loose or worn-out brake hardware, such as brake caliper bolts or brake pad retaining clips, can cause the brake pads to vibrate and rub against the rotor, leading to a screeching sound. |
Symptoms of Brake Screeching
Brake screeching is often accompanied by other symptoms, including:
- A high-pitched squealing or screeching noise when you press the brake pedal
- A grinding or scraping sound when you release the brake pedal
- A vibration or pulsation in the brake pedal or steering wheel
- A decrease in braking performance or a spongy brake pedal
