Brake Wear Your Oldsmobile has front disc brakes and rear drum 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 firmly). I NOTICE: Continuing to drive with worn-out brake pads could repair. result costly in brake 1 1 Some driving conditions or climatesmay cause a brake squeal when the brakes are first applied or lightly applied. This doesnot mean something is wrong with c~ your br. k es. 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. Your rear drum brakes don't have wear indicators, but if you ever hear a rear brake 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. The brake wear warning sound means that soon your brakes won'twork well. That could leadto an accident. When you hear the brake wear warning sound, have your vehicle serviced. 6-29
