Avoid needless heavy braking.Some people drive in spurts - heavy acceleration followedby heavy braking -rather than keeping pace with traffic. This is a mistake. Your brakes may not have timeto cool between hard stops. Your brakes will wear much faster if you do a lotof heavy out braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate lot of unnecessary braking. That means a better braking and longer brake life. If your engine everstops while you're driving, brake normally but don't pump your brakes. If you do, the pedal may get harder push down. If to your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up,may take longer it to stop and the brake pedal will be harder push. to Anti-Lock Brakes (ABS) Your vehicle has an advanced electronic braking system that can help you keep it under control. When you start your vehicle and begin drive away, to you may hear a momentary motor or clicking noise. This is the ABS system testing itself. Here's how anti-lock works. Let's say the road is wet. You're driving safely. Suddenly an animaljumps out in front of you. You slam on the brakes. Here's what happens with ABS. A computer senses that wheels slowing down. If oneof the wheels is are about to stop rolling, the computer will separately work the brakes at each front wheel and at the rear wheels. The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. You can steer around the obstacle while braking hard. 4-6
