Comment

On a down grade, use the engine brake by shifting down to a lower gear. This relieves the service brakes. Under no circumstances change to idle! Because idling puts the engine brake out of action, thus the service brakes could overheat. In addition, the brake booster cannot work when the ignition is switched off. This considerably lengthens the braking distance.
