i just noticed today because its the first time i opened my window for a long time, but when i start driving, theres a squeeking sound... like it sounds like those shopping karts when u push it, it squeeks, but when i push the brakes, the squeek stops. i had a mechanic change the turning belt. i recently changed my brake pads... will that be something that can cause the noise? its so embarassing driving a new car with squeeking sound
