Why are my brakes squealing?
A continuous high-pitched squeal while you’re driving is usually the sound of a built-in wear indicator telling you that it’s time for new brake pads. As the pads wear down and gets thinner, a small metal tab contacts the rotor surface like a needle on a vinyl record to warn you it’s time for new pads.
Why do my brakes Squeak After sitting for a long time?
Most brakes squeak after sitting overnight. This is usually due to moisture from rain, dew, or condensation that collects on the surface of the rotors. When moisture collects on the brake rotors, it causes a thin layer of rust to form on the rotor surface.

Most brakes today are disc brakes, where a pad presses against a disc or rotor to stop the car. The first three squeaks described here come from disc brakes. Many cars have drum brakes on the back wheels, where a curved “shoe” presses against a hollow drum to stop the car.

Why does my brake pad squeak when I panic stop?
A lot of brake pads have metal fibers in them. If there’s an area on the pad where the metal fibers are too close to one another, this can cause squeaking. The pad will typically wear past this point, and then the squeaking will go away. Panic stopping can leave a glossy finish on the brake pad.
