Caution: Refer to

Caution: Brake fluid may be irritating to the skin or eyes. In case of contact, take the following actions:

Notice: Do not use fluid that has a petroleum base. Do not use a container that has been used for petroleum based fluids or is wet with water. Petroleum-based fluids cause swelling and distortion of rubber parts in the hydraulic brake system and water lowers the brake fluid's boiling point. Keep all fluid containers capped to prevent contamination.

Use Delco Supreme 11 Brake Fluid (GM P/N 1052535) or an equivalent DOT-3 motor vehicle brake fluid.

Always store brake fluid in a closed container. Never use previously opened containers of stored brake fluid. Always use new brake fluid from a sealed container. Brake fluid left in open or improperly sealed containers will absorb moisture. Moisture can lower the brake fluid boiling point, causing the following problems:

Improper or contaminated brake fluid may boil or may deteriorate rubber components in the hydraulic brake system.

Evidence of rubber deterioration occurs in the following areas:

If rubber deterioration is found, replace all rubber parts in the brake system. Check for brake fluid on the brake linings. Replace the brake linings that are contaminated with brake fluid.

If the brake fluid is contaminated and the master cylinder piston seals are good, check for leaks and excessive heat conditions. If no leaks or excessive heat conditions are found, flush the brake system.

To flush the brake hydraulic system, run new brake fluid through the brake system. Continue until the brake fluid at each bleeder valve comes out clear. Flush the brake hydraulic system for the following reasons:
