Brake Wear Your vehicle has front disc brakes and rear drum brakes. Disc brake padshave 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 firmly). Notice: Continuing to drive with worn-out brake Dads could result in costlv brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied, This does not meansomething is wrong with your brakes. See Caliper/Knuckle Maintenance inspection on page 6-23. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to GM torque specifications. Your rear drum brakes don't have wear indicators, but if ever hear 3 rear brake rubbing noise, have the rear brake linings inspected immediately. 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 brake pads replaced, have the rear brakes inspected, too. YOU The brake wear warning sound means that soon your brakes won't work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced. Brake lininqs should alwavs be replaced as complete axle sets. See Brake System Inspection on page 6-23. 5-37
