Q: brakes on 2003 Toyota Corolla

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I had pad and brake rotors replaced in Nov 2007, now I am being told to repair again at a cost of $422.95. I now have only 45000 miles on car. Brought the car in because of scraping noise. Please help with explanation. thanks

Sounds like the rear pads have worn down to metal to metal contact, thats where the scraping noise is coming from, the brake pad has a friction material bonded or riveted to a backing plate and when you push on the petal it slows down your car by friction and when the brake pad wears down too far the metal backing plate hits the brake rotor, did you have front and rear brakes replaced in 2007? brakes wear faster if driving up and down hilly areas I usually change mine every 35 to 40 thousand miles so I don't need to replace rotors. Try Napa brand brake pads they seem to last longer.
