I had recently had my brakes checked out and replaced following my mechanic's $800 recommendations.
I had had two brake pads replaced on the front tires and on the back tires I had the brake pads and rotors replaced.
Ever since the replacement, there is this very loud whistling noise that comes from the tires when I brake (I am not sure which tire(s), but I think it may be one or both of the back ones—again, not sure). I've never had this happen in the past.
My question is, should I be concerned about this whistling noise?
