Brake squealing is often a sign of worn brake pads, which are not expensive to replace.

I have been hearing a loud squeal every time I brake, and sometimes even when I am not applying the brakes. This is a recent problem. What are the reasons, and is this a sign of bigger problems to come?
Brake squeal is not an uncommon problem and is usually not difficult to resolve. Often, it is a sign of worn front brake pads. If so, replacing them with new ones should immediately eliminate any noise.
Ensure the replacement pads are of a make recommended by the vehicle manufacturer or from a well-known high-quality brand.
On the whole, disc brake pads or drum brake shoes are not costly components, and saving a few dollars with cheap unknown brands may not be worth the risk.
Brake dust build-up is another cause of squealing noises. A thorough clean-up around the callipers is a simple and quick task to restore noiseless braking.
Some calliper mounts involve shims, pins or clips. These should be inspected for corrosion or damage. Most of these parts are inexpensive and should be replaced during a periodic brake pad change. Some of these components also need to be lubricated to help prevent squealing.
What you should really be concerned about is a scratchy, grinding noise during braking. This might be caused by completely worn-out brake pads, which expose the steel mounting plates. These exposed plates can destroy the brake discs very quickly.
If you hear this noise, do not drive the car any farther.
