Your Driving and the Road Disc Brake Wear Indicators (CONT.) Rear Drum Brakes Your rear drum brakes don't have wear indicators, but if you ever hear a rear brake rubbing noise, have rear brake the 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. Brake Pedal Travel See your dealer if the brake pedal does not return to normalheight, or if there is a rapid increase in pedal travel.This could be a signof brake trouble. 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. 152
