Daily Q&A: How big of a deal are squeaking brakes?

How concerned should I be when my brakes start squeaking?

Squeaky brakes can mean several things. Here's a review by Consumer Reports:

• If you hear squealing only during braking, especially light braking, it's probably caused by a vibration at the brake pads. Squealing doesn't affect your braking performance and, while it's annoying, it is usually nothing to worry about and can happen even with new pads.

If you hear a similar high-pitched squeal from the brakes while the car is moving but it stops when you step on the brake pedal, it can be a sign that your brake pads have worn down and need changing soon.
