The Anatomy of a Squeaking Brake
A brake system is made up of several components, including the brake pads, rotors, calipers, and brake fluid. When you press the brake pedal, the brake pads are forced against the rotors, creating friction that slows down the vehicle. However, when the brake pads wear down or become misaligned, they can start to squeak.
Brake Pad Wear and Tear
Brake pads are made of a friction material that’s designed to wear down over time. As the pads wear down, they can start to squeak, especially when they’re not properly aligned with the rotors. This can cause the brake pads to vibrate and make a squeaking noise when you press the brake pedal.
Causes of Brake Pad Wear
- Worn-out brake pads
- Incorrect brake pad alignment
- Overheated brake pads
- Brake pad contamination
Brake Rotor Wear and Tear
Brake rotors are made of a metal material that’s designed to withstand the heat and friction generated by the brake pads. However, when the rotors become warped or excessively worn, they can start to vibrate and make a squeaking noise when you press the brake pedal.
Causes of Brake Rotor Wear
- Warped brake rotors
- Excessively worn brake rotors
- Brake rotor overheating
- Brake rotor contamination
Symptoms of a Squeaking Brake
A squeaking brake can exhibit a range of symptoms, from a mild squeak to a loud, screeching noise. Here are some common symptoms to look out for:
Common Symptoms
- Squeaking or screeching noise when pressing the brake pedal
