Some driving conditionsor climates may cause a brake squeal when the brakes are first applied or lightly applied. This doesnot mean something is wrong with your brakes. Properly torqued wheel nuts arenecessary to help prevent brake pulsation. Whentires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications. Brake linings should always replaced as complete be axle sets. See "Brake System Inspection"in Section 7 of this manual under Part C "Periodic Maintenance Inspections." Replacing Brake System Parts The braking system on a modern 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 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, 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 the worse. The braking performance you've come to expect can changein many other ways if someone puts in the wrong replacement brake parts. 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. Battery Every new Buick has a Delco Freedom@ battery. You never have to add water to one of these. When it's time for a new battery, we recommend a Delco Freedom battery. 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. ~ 6-31
