A Brake Pedal Travel LAUTION: The brake wear warning sound means that sooner or later your brakes won't work well. Thal 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 rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a moderate brake stop, your disc brakes adjust for wear. If you rarely make a moderate or heavier stop, thenyour brakes might not adjust correctly. If you drive in that way, then -- very carefully -- make a few moderate brake stops about every1000 miles (1600 km), so your brakes will adjust properly. NOTICE: Continuing to drive with worn-out'-ake patcould result in costly brake repair Braking in Emergencies Some driving conditions climates may cause abrake or squeal when the brakes are first applied or lightly applied. This doesnot mean something is wrong with your brakes. Brake linings should always be replaced as complete axle sets. At some time,nearly every driver gets into a situation that requires hard braking. If you have anti-lock, you can steer andbrake at the same time.However, if you don't have anti-lock, your first reaction -- to hit the brake pedal hard and hold it down -- may be the wrong thing to do. Your wheels can stop rolling. Once they do, the vehicle can't respond to your steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling.
