Causes of Disc Brake Squeal
Disc brake squeal can be caused by a variety of factors, including:
Worn-Out Brake Pads
Worn-out brake pads are one of the most common causes of disc brake squeal. When brake pads become worn, they can cause the brake caliper to vibrate, leading to a high-pitched squeal. This is often accompanied by a grinding or screeching noise when the brakes are applied.
Signs of worn-out brake pads include:
- Visible wear on the brake pads
- Increased brake pedal travel
- Soft or spongy brake pedal feel
Misaligned Brake Rotors
Misaligned brake rotors can cause the brake pads to vibrate, leading to a high-pitched squeal. This is often accompanied by a grinding or screeching noise when the brakes are applied.
Signs of misaligned brake rotors include:
- Visible wear on the brake rotors
- Increased brake pedal travel
- Soft or spongy brake pedal feel
Brake Caliper Problems
Brake caliper problems can cause the brake pads to vibrate, leading to a high-pitched squeal. This is often accompanied by a grinding or screeching noise when the brakes are applied.
Signs of brake caliper problems include: (See Also: What Is Brake Hold in Honda Civic? Explained Simply)
