the fluid level goes back up.The other reasonis that fluid is leaking out of the brake system.If it is, you should have your brake system fixed,since a leak means that sooner or later your brakes won't work well, or won't work at all. So, it isn't a good idea "top off' to your brake fluid. Adding brake fluid won't correct a leak. If you add fluid when your linings worn, then are you'll havetoo much fluid when you new brake get linings. You should add (or remove) brake fluid, as necessary, only when workis done on the brake hydraulic system. What toAdd 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. @ L NOTICE: Don't let someone put in thewrong kind of fluid. For example, just a few drops of mineral-based oil, such as engine i oil, n your brake system can damage brake system parts so badly thatthey'll have tobe replaced. Brake fluid can damage paint,so be careful not tospill brake fluidon your vehicle. If you do, washit off immediately. See "Appearance Care" in the Index. When your brake fluid falls to a low level, your brake warning light willcome on. A chime will sound if you try to drive with this warninglight on. See "Brake System Warning Light"in the Index. 6-29
