Car brakes work by applying friction between two surfaces converting the motion (kinetic energy) to heat and slowing down the car. Traveling a downgrade for long distances can result in the brakes overheating and the friction surfaces grinding down and/or burning out. The correct thing to do is to downshift your transmission to prevent the vehicle from gaining too much downhill speed.

Car BRAKES (check spelling) can overheat when braking for an extended period of time, without a cooling off period. Watch a NASCAR race at night- you can see the brake rotors glowing red hot.
