If you add fluid when your linings are worn, then you'll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. 0 0 a 1 LAUTION: If you have too muchbrake flui,, I . ; n sblll orl a the engine.

DOT-5 silicone brake fluid can damage your vehicle. Don't use it. Don't let someone put in the wrong kind of fluid. For example, just afew 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. Brake fluid can damage paint, so be careful not to spill brake fluid onyour vehicle. Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top qualityand work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your Buick does when it is new. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don't, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the When your brake fluid falls to a low level, your brake warning light will come on. See "Brake System Warning Light" in the Index. What to Add: When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11@ (GM Part N0.1052535). Use new brake fluid from a sealed container only. 234
