Close-up of a disc brake on a car
On automobiles, disc brakes are often located within the wheelThe disc brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic, is connected to the wheel or the axle. To stop the wheel, friction material in the form of brake pads (mounted in a device called a brake caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop.

A friction material (the actual pad that comes into contact with the brake rotor) is bonded/riveted to a backing plate (that the caliper holds in place and is used to apply the brake pressure).
They used to be made of asbestos, but now are made with a number of real "chemistry geek" sounding materials that perform better and are less messy.

There are many different materials used in brake pads from sintered metal to carbon fiber and now ceramics. Most are proprietary formulas that differ by the manufacturers. Could be anything except asbestos.

They cut a piece of metal of the correct dimensions. Then they cut brake pad material to fit. The pad is then riveted to the metal and it is ready for the market. Pops
