I had my rear pads and rotors replaced at 30,000 miles, stock pads and rotors, by the dealership. I am now at about 44,000 miles, and the dealership mechanic said that we have only 10% of the brake pad remaining and that we should replace the pads and rotors. The 30,000 service was in June 05. This seems quite a bit soon for me, as the first set of rear pads lasted 30,000 miles. Any advice would be appreciated.
