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.

Why do my brakes squeak after new pads?
Normal New Brake Squeal
Likewise, overnight condensation accumulating on the metal rotors can create surface rust that requires a few braking occurences in the morning to wipe away. These parts can make a squeaking noise when covered with surface rust. The noise should subside as you drive.
Do new brake pads and rotors make noise?
One of the major cause of brakes noise after new pads and rotors is having excess brake dust that is trapped between the caliper and the rotor. ... And when these dusts are heated, they will definitely make an annoying noise. Sometimes it might be nothing to you and the sound will go away on its own.
Can rotors cause squeaking?
Rusted Brake Rotor
Over time, your car's rotors can lose their smoothness, which is another common cause of brake squeaking. Rust and other debris can cause the squeaking noise. If this is a problem on your vehicle, the rust or dirt can be filed off by your local mechanic.
How do I stop my brand new brakes from squeaking?
If your brakes are new and still squeaking, the fix may be as simple as greasing the contact points. This requires removing the brake pads from the calipers (see How to Change Your Brake Pads and Rotors), then applying brake grease to all the contact points.
Why do my brakes squeal at low speeds?
The squeaking noises when braking at low speed is caused by high-frequency vibration of the pads against the rotating disc. When the caliper clamps against the rotating disc, it generates friction which leads to vibration. So, the squeaking noise will increase if the brake pads are mounted more tightly in the caliper.
How long does it take to break in new brakes and rotors?
"Bedding-in new pads and rotors should be done carefully and slowly... Most brake pad compounds will take up to 300-400 miles to fully develop an even transfer film on the rotors."
What can I spray on my brakes to stop squeaking?
Permatex Disc Brake Quiet stops brake squealing by dampening vibration at the caliper/brake pad interface. While providing a tighter fit and allowing for easier disassembly it also protects against corrosion.
What do bad rotors sound like?
One of the first symptoms commonly associated with bad brake rotors is noise. If the rotors are warped or severely worn, they may produce squealing or squeaking sounds. Usually warped rotors will produce a squeak, while severely worn rotors will produce a scraping sound.
What does a bad caliper sound like?
If the car is squealing rather than clunking it may also be the sign of a bad caliper. Most people know that a car needs new brake pads if their car makes a noise when the brakes are applied. However, if something is wrong with the caliper, you will hear this noise when you are not using the brakes.
