What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 1 1 (GM Part No. 12377967). Use new brake fluid from a sealed container only. @ NOTICE: Using the wrong fluid can badly damage just brake system parts. For example, a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they'll have to be replaced. Don't let someone putin the wrong kind of fluid. If you spill brake fluid on your vehicle's painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash itoff immediately. See "Appearance Care" in the Index. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. 1A CAUTION: 1 With the wrong kind fluid in your brake of system, your brakes may not work or they well, may not even work at all. This could causea crash. Always use the proper brake fluid. 6-30
