Certain sport utility vehicles were built with a left-front brake pipe with a circumferential score at a random location along the length of the pipe as the result of the manufacturing process. If the brake pipe partially or fully fractured, brake pedal travel would immediately increase and front brake performance would be reduced.
Dealers will replace the left-front brake pipe. Owner notification began on May 29, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or Oldsmobile at 1-800-442-8006.
