Some driving conditions or climates cause a brake may squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Your rear drum brakes don't have wear indicators, but if you ever hear a rearbrake rubbing noise, have the rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. Replacing Brake System Parts The bralung system on a modem 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. 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 andyou 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 balance between your front and rear brakes canchange -- 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. 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. Brake Adjustment Every time you apply the brakes moderately, with or without the vehicle moving, your brakes adjust for wear. 6-23
