Hi Sarah:
Is the scraping noise gone? You know, it isn't uncommon for the backing plate behind the brake rotor to get bent or rust allowing it to touch the brake rotor. That will make a scraping noise.
Are you still getting a pull to the left when braking since the tire pressure was adjusted? Also, it's a good idea to pick up a tire pressure gauge at a parts store and keep in in the vehicle. They are about the size of a pen and very inexpensive. If you open the driver's door, you will see a label on the door frame that indicates the original equipment tire size and the recommend tire pressure. If you have a gauge, you can keep and eye on it.
Let me know.
Joe
