Caution: Use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid from a clean, sealed container. Do not use fluid from an open container that may be contaminated with water. Improper or contaminated fluid could result in damage to components, or loss of braking, with possible injury.

Notice: When filling the master cylinder, use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid. Do not use a container which has been used for petroleum based fluids, or a container which is wet with water. Petroleum based fluids will cause swelling and distortion of rubber parts in the hydraulic brake system, and water will mix with brake fluid, lowering the boiling point. Keep all fluid containers capped to prevent contamination.

Important: Flush the hydraulic brake system under the following conditions:

   • The DOT rating of the brake fluid is incorrect.
   • The brake fluid contains water or mineral oil.
   • The rubber brake components are swollen, indicating contamination of the brake fluid.

  1. Replace all damaged rubber brake components.
  2. Use 0.94 liter (1 quart) of Delco Supreme 11® Brake Fluid, GM P/N 12377967, or equivalent DOT 3 brake fluid, in order to flush the hydraulic brake system.
  3. Use the Manual Bleeding Procedure in order to flush the hydraulic brake system. Refer to Hydraulic Brake System Bleeding .
