I bough 2001-GMC-truck-sonoma. As a left over. On January 11, 2002,is the date I received it ,that is when I bough it. On April 10, 2002 @\at 1160 miles,they replaced both of the front brake rotors. On August 14, 2003 at 7745 miles they replaced both of the rear brake rotors, and turned front rotors. Now as of jan212006,there is only 17,868 miles on the truck, it's always be garage keeped. And well cared for. It's still has the new small inside, now all 4 of the rotors and brakes haves to be replacd.
