Checking Brake Flu: What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 (GM Part No. 1052535). Use new brake fluid from a sealed container only, and always clean the brake fluid reservoir cap before removing it. @ A CAUTION: With the wrong kind fluid in your brake of 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. You can check the brake fluid without taking off the cap. Just look atthe window on the brake fluid reservoir. The fluid level should be above MIN. If it isn't, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above MIN and below the top of the window. 6-32
