The image shows an infrared picture of a disc brake on a car after it has been driven and stopped. Heat is created when the brake pad comes in contact (rubbing) with the brake disc.
What causes the disc brake to heat up to almost 200°F ?
B) friction causes the heat, but is also the force that stops the car from crashing! The pads, disc, drum, etc. of the brake system are designed to absorb most of the heat produced from the friction of braking.
