When driving there is a noise that sounds like air coming out of a tire in my car and it stops when the brakes are pushed?

The noise you’re hearing could be related to a few different issues, such as a problem with the brake components or a potential air leak in the braking system. It's possible that worn brake pads or a sticking caliper are causing the sound, which may change when pressure is applied to the brakes. Additionally, check for any issues with the wheel bearings or tire itself, as these can also create similar noises. It's advisable to have a mechanic inspect the vehicle to ensure safety and proper functioning.
