Brake Pads
Brake pads are part of disc brakes in automotives and other places. Brake pads are made of steel plates with friction material put on the surface that faces the rotor.
How it works
They change kinetic energy to thermal energy with friction. Two brake pads are inside the brake facing the rotor.[1] When the brakes are squeezed, it squeezes the two brake pads together on the rotor which slows and stops the vehicle.
History
The idea of brake pads or disc brakes was around somewhere in early 1902 with a patent from Frederick W. Lanchester.[2] But they costed too much and were inefficient compared to drum brakes. They were not used as much until after World War II.[3] Their technology improved and it braked better than drum brakes did. In 1953, a Jaguar using brake pads won the 24 Hours of Le Mans Grand Prix of Endurance Race.[3][4] The Jaguar's victory is thought to be because of the disc brakes which let the driver turn faster and brake later.
