To Check BrakeFluid m You can check the brake fluid without taking off the cap. Just look at the windows on the brake fluid reservoir. The fluid levels should be above "MIN." If they aren't, have your brake system checked to see if there is aleak. After work is done on the brake hydraulic system, make sure the levels are above '"IN'' and below the top of each window. What to Add When you do need brake fluid, use only DOT-3 brake fluid - such as (GM P a r t No.1052535). Use new brakefluid from a Delco Supremel l @ sealed container only, andalways clean the brake fluid reservoir cap before removing it. 0 Don't let someone put in the wrong kind of fluid. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they'li have to be replaced. Brake fluid can damage paint, so be careful not to spillbrake fluid on your vehicle. If you do, washit off immediately. See "Appearance Care" in the Index.
