What is a Brake Pad Rattle?
A brake pad rattle is a common phenomenon where the brake pads, which are designed to slow down or stop your vehicle, produce a rattling or vibrating sound when you apply the brakes. This sound is usually accompanied by a slight vibration or wobbling sensation in the brake pedal or steering wheel.
Causes of Brake Pad Rattle
There are several reasons why your brake pads might start rattling. Some common causes include:
Worn-out brake pads: Over time, brake pads wear down, and the metal backing plate can start to rattle against the brake rotor.
Loose brake hardware: If the brake caliper or brake pad retaining clips are loose, they can cause the brake pads to vibrate and produce a rattling sound.
Warped or uneven brake rotors: If the brake rotors are warped or uneven, they can cause the brake pads to vibrate and rattle.
Brake pad wear indicators: Some brake pads have built-in wear indicators that produce a rattling or scraping sound when the pads are worn down to a certain level.
