Friction always creates heat. Brakes and tires depend on friction to work, but friction can also damage a car's mechanics. For example, the engine is susceptible to the heat caused by friction, and mechanics devise ways to protect against friction while trying to get the greatest amount of horsepower without damaging the car.
