Some driving conditions or climates cause a brake may squeal when the brakes are first applied or lightly applied. This doesnot mean something is wrong with your brakes. Free movement of brake calipersand properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake calipers for movement, 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 tiresare removed for rotation or changing. Whenyou have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. :a1 Pedal Travel ~ see your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by backing up and firmly applying the brakes a few times. 6-29
