Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmy). Some driving conditions or climates cause a brake may squeal when the brakes are firstapplied or lightly applied. This doesnot mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications. I Brake linings should always be replaced as complete axle sets. See "Brake System Inspection" in Section 7 of this manual under Part C "Periodic Maintenance Inspections." The brake wear warning sound means that soon your brakes won't work well. That could lead to an accident. Whenyou hear the brake wear warning sound, haveyour vehicle serviced. Brake Pedal n a v e l See yourdealer if the brake pedal does not return to normal height, or if there is a rapid increasein pedal travel. This couldbe a sign of brake trouble. I NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust forwear. 6-32
