Summary: Certain trucks, sport utility vehicles, and vans equipped with Boch Hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the Hydro-boost assembly durring normal operating conditions.

Consequence: If a separation occurred and the hood were open, fragments from the accumulator could cause injury to people in the immediate area. The presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circut of the booster assembly. The loss of fluid would cause increased steering and breaking effort and a crash may occur without prior warning.

Remedy: Dealers will test the Hydro-boost assembly for functional opperation of the two-function valve. If the Hydro-boost assembly fails the test, the dealers are to replace the assembly. The recall is expected to begin durring March 2005. Owners should contact Chevrolet AT 1-800-630-2438, GMC Trucks at 1-866-996-9463 AND Hummer AT 1-800-732-5493.
