The brakes gets energy, it may kinetic energy of the moving part or potential energy created by objects are brought down by elevators etc. to perform the braking action. A disc brake is a type of brake that uses calipers to squeeze the pairs of pads against a rotating disc in order to create friction that slower the rotation of a shaft such as a vehicle axle, either to reduce its rotational speed or to make it stationary. The energy of motion is converted into waste heat which must be dispersed. Disc brakes are commonly used for vehicle braking but they are applicable to almost any rotating shaft. The brake disc (or rotor in American English) is usually made of cast iron, but in some cases it is made of composites such as reinforced carbon or ceramic matrix composite materials. It is connected to the wheel or to the axle. Brake pads are the friction material, mounted on a device called a brake caliper, is forced mechanically, hydraulically, pneumatically, or electromagnetically against both sides of the disc to retard the wheel. Friction causes the disc and attached wheel to slow or stop. Brakes convert motion to heat, if the brakes get too hot & they become less effective, a phenomenon known as brake fade
