............Usually means the brake pads have worn down to the metal.
it's probably still stuck there=] and b/c there is metal that is inside all tires..
This may be a wheel bearing problem.
A warped rotor makes a scraping noise. The rotor will no longer sit flush with the wheel and what ever it rubs against will create a loud metal scraping noise.
Assuming this vehicle is front wheel drive, you probably have a bad passenger side half shaft.
The energy in a crash can be transferred in a variety of ways. The most significant way is through mechanical and physical deformation. In a head on collision between two cars, the energy travels through the front of each car, crumpling the metal and machinery. Energy can then be transferred in the form of heat. Although this energy isn't as significant as mechanical energy, during the moment of impact there will be a trace amount of heat created through the scraping of metal. Energy is also transferred through sound waves. When two vehicles collide, the sound of the scraping metal is the transfer of some of the energy through the air.
No, usually a scraping sound indicates the starter is dragging and needs to be replaced.
The scraping of chains
have the back brakes checked sometimes they can sound like the front
The passenger side front tire may be rubbing on the inner fender.
Probably your brake pad came off.
By shaking, scraping, or striking the instrument itself
A small rock or pebble may be stuck in tire's tread.
