What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to Part D: Recommended Fluids and Lubricants on page 6-75. Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from enteri-- the reservoir. Notice: Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, suchas engine oil, in your brake system can damage brake system parts so badly that they'll have tobe replaced. Don't let someone put in the wrong kindof fluid. 9 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. With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid. 5-40
