Why do brakes squeak?
Today s cars are equipped with front wheel disc brakes; some models even have 4 wheel disc brake systems. Disc brakes work much like a modern bicycle s brakes. Brake squealing and noises are common with various causes. Most often it is caused by dust and high frequency vibrations of the brake pads, much like the way a cricket makes noises by rubbing its legs together. Worn brake linings also tend to be noisy. Brake systems should be checked regularly and worn parts replaced before ruining expensive calipers and rotors.
