Understanding Brake Squeaking
Brake squeaking, also known as brake noise, is a high-pitched sound that occurs when the brake pads or shoes make contact with the rotor or drum. It’s usually caused by the friction between the brake components, which can be due to a variety of factors, including worn-out brake pads, misaligned brake calipers, or even a faulty brake master cylinder.
Types of Brake Squeaking
There are several types of brake squeaking, each with its own unique characteristics. Some common types include:
- High-pitched squeal: This is the most common type of brake squeaking, characterized by a high-pitched sound that can be heard when the brakes are applied.
- Low-pitched grinding: This type of brake squeaking is characterized by a low-pitched grinding sound that can be heard when the brakes are applied.
- Screeching: This type of brake squeaking is characterized by a loud, screeching sound that can be heard when the brakes are applied.
Causes of Brake Squeaking
Brake squeaking 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 brake squeaking. When the brake pads wear down, they can become uneven, causing the brake caliper to vibrate and produce a squeaking sound.
Signs of Worn-Out Brake Pads
Some common signs of worn-out brake pads include:
- Squealing or grinding noise when the brakes are applied.
- Brake pedal feels spongy or soft.
- Brake light comes on the dashboard.
Misaligned Brake Calipers
Misaligned brake calipers can also cause brake squeaking. When the brake caliper is not properly aligned, it can cause the brake pads to vibrate and produce a squeaking sound. (See Also: How Long Should Rear Brake Pads Last? – The Ultimate Guide)
Signs of Misaligned Brake Calipers
Some common signs of misaligned brake calipers include:
- Squealing or grinding noise when the brakes are applied.
- Brake pedal feels spongy or soft.

Faulty Brake Master Cylinder
A faulty brake master cylinder can also cause brake squeaking. When the brake master cylinder is faulty, it can cause the brake fluid to leak, leading to a squeaking sound.
Signs of Faulty Brake Master Cylinder
Some common signs of a faulty brake master cylinder include:
- Squealing or grinding noise when the brakes are applied.
- Brake pedal feels spongy or soft.
- Brake light comes on the dashboard.
