When you press on the brake pedal in your car, you might hear a sound that seems to come from the air. What’s happening is that the brake pedal is pressing down on a metal plate, which in turn is pressing down on a rubber pad.

This in turn creates the sound that you’re hearing.

There are a few different things that could cause a noise when you brake. Worn brake pads will cause a noise called brake squeal. This is caused by metal on metal contact and is usually an indication that the pads need to be replaced. If the pads are worn down too far, they can damage the rotors, which can also cause a noise.

Another common noise is a hissing sound. This could be caused by a number of things, including a brake line leak, a bad brake caliper, or a seized brake caliper.
