Hydraulic System: Service Precautions

Important: Use only Delco Supreme II Brake Fluid GM P/N 123777967, or equivalent DOT-3 brake fluid.

Do not use power steering or transmission fluid in the brake system.
Do not re-use brake fluid accumulated during brake system bleeding.
Always store brake fluid in a closed container. Reseal brake fluid containers immediately after use. Do not use brake fluid left in an open or improperly sealed container, because it absorbs moisture or can become contaminated.
