One problem related to brake fluid leak has been reported for the 2002 Chevrolet C/k Pickups. The most recently reported issues are listed below.
Started out to work one morning,truck performed fine. Stopped for gas restarted truck,noticed that brake pedal went down considerable amount further than normal ,and it took more foot pressure to stop. Continued to work,worked,drove home. By the time I got home brake pedal went to floor,and had no stopping power. Next morning checked brake master cylinder reservoir ,it was empty. I than noticed puddle of fluid under driverside of truck. I checked under the hood and noticed to my surprise rust through on the steel brake line. Dealer was contacted was told they would look at it. Had truck towed to dealer,service manager wanted guarantee of payment of 40 dollars and change to look at it,to confirm what I already knew that the brake lines were rusted. They said this was normal and would not take any responsibility to repair it,only to offer small credit towards parts,which amounts to nothing. I don't know where to go now ,and are making arrangements to have it towed back home.
