What might be causing this scraping noise? A couple days ago my brake light turned on in my dash. My brakes have felt a little splotchy since I bought the car 3 months ago. I didn't feel I was having any problems with my brakes though. Then yesterday, I went to a restaurant who's parking lot was not what I would call flat. I parked nose first pointing down hill on pitch of about 10 to 15 degrees. The car is automatic, I applied the E-brake just to be sure the car wouldn't have a problem with rolling. When I got back into the car, I put it in reverse, drove back a car length before putting it in forward. Put the car in drive and started to go forward, and I heard a loud scraping noise coming from outside. (I'm not sure if it happened while in reverse as well) Over about 30mph it quiets down a little. Under 20mph its very apparent. Braking to zero, its very much there, and as the car slows down, the scraping is longer and more drawn out. I stopped in a parking lot with my girl friend to have her drive it around. It's definitely coming from the front passenger side wheel. I cant hear it from anywhere else on the vehicle as loud as I hear it from there. The noise also appears to happen in the same exact location. Using the valve stem as a marker, I would say it scrapes from 11 o'clock to 5 o'clock. What could it be?
This is typical of needing a brake job. The linings are worn down so far that the metal backing plates are grinding on the rotors. That means the rotors will most likely need to be replaced too. The good news is the cost has come down a lot for them in the past years.
The place to start is by having the brake system inspected. The shop will give you a detailed estimate of the cost of the standard brake job plus any additional parts and services that are needed.
