What to Add: When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 1 s (GM part No.1052535). Use new brake fluid from a 1 sealed container only. REPLACING BRAKE SYSTEM PARTS The braking system on a modern vehicle is complex. Its many parts have to beof top quality and 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 Cadillac does when it is new.When you replace parts of your braking system -- for example, when your brake linings wear down and you haveto have new ones put in -- be sureyou 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 balance between your front and rear brakes can change, for theworse. The braking performance you've come to expect can change in manyother ways if someone puts in the wrong replacement brake parts. 286
