I have a 05 Aveo LS with 116k miles on it. For about a year now I have been having problems with my brakes. The pedal would go to the floor with very little stopping power. I keep getting the runaround from the dealor. Finally the dealor just said I need new brake pads on all 4 wheels. I did not trust them and took it to another local shopand they said I had 75% of my pads left the looked at the car and found the rear drums are not self adjusting themselves. They tested the auto adjuster and everything works fine. They found there is a design defect in the auto adjuster that keeps it from adjusting the drums. They don't know of a fix for it. So they just manually adjusted them. Guess I will have to get them adjusted manually every so often.
