3 weeks after i got back from iraq, i notice my right front brake started to make a squeeky sound..upon inspection, my brake pads seems to be worn down so i changed them...went for a ride after and still making that squeeky sound, so i jacked up the car and see what was wrong, brake pads seems to be sticking on the rotor, so i decided to let the pros take care of it, later on i got the car back with new brake pads, went for a test drive once again and my car was still making that noise, i notified the shop so they took it for a drive and said it was fine and they didn't hear any noise coming from the brake, so once again i took it for a test drive, put it in neutral and still hears that noise from the brake, im jus so puzzled cause the shop told me it was good to go but its not....my guesses are either my rotors are warp or air in the brake lines found its way somehow....jus need you guys input on this, any advice would be greatly appreciated..thanks
