Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality brake parts. When you replace parts of the braking system - for example, when the brake linings wear down and you need new ones put in - be sure you get new approved replacement parts. If you do not, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between the front and rear brakes can change - for the worse. The braking performance you have come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Vehicle Storage If you are not going to drive your vehicle for 25 days or more, remove the black, negative (−) cable from the battery. This will help keep the battery from running down. {CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting on page 425 for tips on working around a battery without getting hurt. Battery Your vehicle has a maintenance free battery. When it is time for a new battery, get one that has the replacement number shown on the original battery's label. We recommend an ACDelco® replacement battery. See Engine Compartment Overview on page 396 for battery location. 424
