Filling the Master Cylinder Caution
CAUTION:
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.
