What to Add When you do need brake fluid, use only DOT-3 brake (GM Part fluid -- such as Delco Supreme l l @ No. 12377967). Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the capbefore removing it. This will help keep dirt from entering the reservoir. NOTICE: 0 0 With the wrong kind fluid in your brake of system, your brakes may not work or they well, may not even work all. This could cause a at crash. Always use the proper brake fluid. Using the wrong fluid can badly damage brake system parts. For example, just few a 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 put in 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 it off immediately. See "Appearance Care" in the Index.
