Hey thanks for stopping by. I don't know if this concern the brakes because last night i drove my car and kept hearing this sound like (grinding metal) everytime i hit the brake pedal to slow down. What are the symptoms of a woring out brake? Help pls.

Most probably this is your brake pads wear indicator. Have your brake pads checked and probably replaced.

Worn brake pads make a high pitched squeaking sound. What you are hearing is the rotors being eaten up, probably from brake pads that are worn beyond tolerances. Change pads and rotors ASAP.
