Parking brake failure involving 2002 Chevrolet Avalanche. There was no damage or injury. However, when brought in for repair, I was given a report that states, according to Chevrolet technical assistance "parking brake is not designed to hold on a down slope and only designed to hold at 8% grade on up slope." This runs counter to the 2002 Chevrolet Avalanche owners manual, section 7-20, entitled "parking brake and automatic transmission park mechanism check which instructs as follows: "park on a fairly steep hill, with the vehicle facing downhill" and proceeds to give steps for checking the parking brake function that create a clear expectation that the parking brake should function "on a fairly steep hill." Since bringing my vehicle for requested adjustment/repair, I continue to find that the parking brake will not hold with the vehicle facing downhill on even a modest slope. Knowing that I cannot rely on the parking brake, for now I will take other steps to assure safety. I am very concerned for other owners of this vehicle... for their safety and the safety of their families. If an owner, unaware of this defect, having a driveway of any modest slope, relies on this vehicle's parking brake... they clearly face the risk of unexpected movement of the vehicle... risking damage to property or to human life.
