Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.

Get one that has the replacement number shown on the original battery's label. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear. Vehicle Storage If you're not going to drive your vehicle 25 days or more, for take off the black, negative(-) cable from the battery. This will help keep your battery from running down. Replacing Brake System Parts The braking system on a mo'dernvehicle 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 wasdesigned and tested with top-quality GM brake parts. 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 approved GM replacement parts. If you don't, yourbrakes 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 the worse. The braking performance you've come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Batteries have acid thatcan burn you and gas that can explode. You can be badly hurt if you aren't careful. See "Jump Starting" in the Index for tips on working around a battery without getting hurt. Contact your dealer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see "Theft-Deterrent Feature" in the Index. 6-33
