Why are my brakes squeaking? Cause
New Brake Parts It is common for new rotors or brake pads to squeak within the first few days before they’re completely broken in.
Damp Brake Pads Brakes often squeak when moisture gets onto the brake pads.
Brake Wear Indicators Most brake pads are designed with steel clips in them called wear indicators. The resulting irritating sound you hear lets you know it’s time to take your car in to get new brake pads.
Worn Brake Pad Insulation and Loose Parts Squeaking can also happen when the material that insulates your brake pads starts to wear down as well as when hoses or rotors come loose.
Glazed Brakes Glazing can occur when the entire brake system gets stuck due to too much friction. Heat builds up and causes your brakes to harden and not perform as well.

HOW DO BRAKES WORK?

Slowing your car down and bringing it to a complete stop is all about using pressure to create friction.

When you press down on your brake pedal, the pressure you apply goes to the brake system’s main cylinder, where it pushes brake fluid out towards your wheels.
Most brake systems are designed with a series of clamps, or calipers, around the rotors of your wheels. These calipers hover just above the rotors, both in front and behind them. When you step on the brake pedal, these calipers press down against the rotors.
Each side of the calipers is fitted with brake pads to create friction when they press up against the spinning rotors. Ultimately, this is what slows your car down and stops it.

WHAT CAUSES SQUEAKY BRAKES?

There’s a couple things that can cause your brakes to sound like nails on a chalkboard.

One innocent cause can be moisture. If you hear squeaking in the early morning but not in the afternoon, it’s likely that it was just dew that settled on your rotors. It may have created a thin layer of rust that your brake pads needed to scrape off. This is nothing to worry about.
The main reason is actually by design.
Brake pads wear down over time. With all that friction from pressing against fast-spinning metal rotors, it’s inevitable that you’ll eventually need to replace them.
Most brake pads are designed with a tiny metal screw or spring called an indicator. Once the pad has worn down enough, this indicator makes direct contact with the rotors and causes the squeaking.
In some cases, the sound can be caused by a mechanical problem with your brakes, but more often than not, the sound is just letting you know that your brake pads are worn down.

WHAT TO DO WITH SQUEAKING BRAKES?

Once you notice that you’re hearing this sound on a consistent basis, your best bet is to take your car in for service.

Most likely, it just needs new brake pads. A technician will inspect the brakes first to make sure it’s not a mechanical problem with the rotors or calipers.
After getting new, quality brake pads installed, you should be good to go for a quiet, squeak-free drive.
