What causes brakes to lock up when hot?

Why are my brakes extremely hot?
The main cause of the brake disc overheating is friction. While the working principle of the braking system is based on friction , with the aggressive driving style it increases. This leads to an increase in the temperature of the brake discs to 600-700 °C.
Are overheating brakes dangerous?

What causes a brake to lock up?

When brakes overheat and lose their effectiveness, the condition is called. Brake fade. As you are driving your stick shift vehicle, your accelerator sticks.
How hot is too hot for brakes?

What to do if your brake caliper is locked up?
If your brakes are locked up its going to be very hot just after driving. The whole area that is affected is going to be very hot. Let the vehicle cool down before attempting to diagnose the problem. Don’t touch a hot rotor or any hot brake component! Injury can occur.
What causes the brake to lock up on one wheel?

This video will give information on how to test each of these components in order to get a better idea of what is causing your brake problem.
Why are my brakes heating up after a tire change?
