Brake Pedal Travel See your dealer/retailer 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 that brake service might be required. Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality brake parts. When you replace parts of the braking system - for example, when the brake linings wear down and you need new ones put in - be sure you get new approved replacement parts. If you do not, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between the front and rear brakes can change - for the worse. The braking performance you have come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, the brakes adjust for wear. 5-44
