2 Underbody Shield problem of the 2000 GMC Sierra 2500

Failure Date: 06/22/2011

Was driving on a local road. Brake pedal went to floor. Was able to stop and drive it home. The line above the gas tank was corroded and had to be replaced. Same thing happened in Dec. 2011. This time the line was corroded against the frame leading to the abs module. This repair hasn't been completed because of expense. I plan to replace the remainder of the lines because they are rusting inside the engine compartment leading to the master cylinder.
