You are traveling down a long, steep downhill mountain road on a hot day and you don't want to wear out your brakes. What is a good way to reduce brake wear?
Answer Shift into a low gear.
Placing the car in low gear will help the car slow down without the use of your brakes, putting the burden more on the engine.
