I wonder if you can help us figure out how to fix my son’s 2002 Volvo S40.
My son bought his first car. It was inspected a week before he bought it, and has about 50,000 miles. It seemed to drive fine when he purchased it, but after a few days, he heard a squeaking/ chirping sound (that seemed to be coming from the left front side of the car) when he accelerated. The sound stops when he brakes hard. He took the car to a mechanic who told him that he needed new brake pads (front and rear). He replaced the front pads, but the sound persisted. He went to another mechanic who told him that the pads were not put on properly and smoothed the rotor. The sound decreased for a short time and then returned. The mechanic says that the rotor looks fine, but is now recommending that he replace it since adjusting the brake pad and smoothing the rotor is not working. I would so appreciate your ideas.
