NOTICE: 0 Brake Wear Your Buick 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 padsare 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). 0 Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brakesystem can damage brake system parts so badly that they'll have to be replaced. Don't let someone put in the wrong kindof fluid. If you spill brake fluid on your vehicle's painted surfaces, the paint finish can be damaged. Be careful notto spill brake fluid f on yourvehicle. I you do, wash itoff immediately. See "Appearance Care" in the Index. I NOTICE: ' C o n k n b g to 'drivewith wornlout brakepads could result'in costly brake repair.
