GENERAL MOTORS recall on BRAVADAENVOY, and TRAILBLAZER models

On certain vehicles, the left front brake pipe may have a circumferential score at a random location along the length of the pipe as a result of an incomplete cutting/processing operation. If the brake pipe at the scoring location corroded to the point that the brake pipe wall became very thin, and application of the brake developed enough pressure to partially or fully fracture the brake pipe, brake pedal travel would immediately increase and front brake performance would be reduced. Correction: Dealer will replace the left front brake pipe.
