Yesterday a United Boeing B-767 made an emergency evacuation after it landed with hot brakes at Chicago's Ohara Airport. After the plane landed & came to a full stop they deployed the emergency slides. There were about 100 people onboard  three of which were injured from the evacuation. Hot brakes after landing occurs more often then you might think. After an abundance of caution flight crews will usually park the aircraft at an isolated area on the airport, or park it at the gate & wait for the airport fire trucks to inspect the brakes. From the cockpit we have an instrument gauge to monitor the temperature of the brakes. Depending on what range or temperature it is will depend if we declare an emergency & evacuate the cabin, or have passengers deplane normally from the gate. Hot brakes can cause loss of braking performance, tire deflation & potentially a fire. Hot brakes is something flight crews take seriously,and are well trained to handle. In most cases the outcome is usually successful & passengers get out safely. What causes these brakes to get hot are many factors such as hot temperature weather, high elevation airports, & excessive wear of brakes at high speeds. In jets pilots shouldn't use brakes until the speed on landing decrease to around 100 knots. If you used brakes at greater speeds there is a chance of brakes heating up. In most cases the brake temperature will cool off on it's own by the time the aircraft taxi to the gate.
