Brake Wear Your vehicle has four-wheeldisc 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 andgo or l be heard al the time your vehicle is moving (except when you are pushing on the brake pedal firmly). Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. 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." Brake Pedal Travel 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. See your dealer if the brake pedal does not return to normal height, or if there is a rapidincrease in pedal travel. This could be a sign of brake trouble. Brake Adjustment As you make brake stops, your disc brakes automatically adjust for wear. I NOTICE: Continuing to drive with worn-out brake pads could resultin costly brake repair. 6-31
