A brake pad is a pad that allows you to stop a car by causing friction to the rotors. The first brake was invented in 1902 for a 12hp Lanchester motor car that was made in 1903. I chose my project on brake pads because I wanted to learn how brake pads worked and what components they had in them. It is very interesting on how they work and how the combined elements in the pads are formed to produce the friction and pressure to the rotors in order for a car to stop. My everyday life is affected by brake pads. I love being around cars and getting to know everything about them. They allow me to go up to high speeds (the speed limit) and allow me to brake in emergency situations.

Brake pads are made out of a steel plates that are bound with the materials like iron oxide, graphite, and fiberglass on the surface of the steel, facing the rotors.
Main Chemicals, Compounds, Components
Lead Sulfide- PbS
Some of the components that make up metallic brakes are iron sulfide, nickel, graphite, steel and fiberglass. These elements are naturally occurring within the periodic table. They can be created in a lab and created by man. They create them by carbon and manganese for iron (C+Mg), steel is made up of nickel, nitrogen, molybdenum, and chromium (Ni+N+Cr+Mo). Nickel is pure nickel (Ni), graphite is made of carbon (C) and Fiberglass is (SiO2). Chemistry plays a role in creating the brake pads because the elements are formed together in order for them to be able to make the chemical reaction in the specific time for a car to stop. The different compounds form a reaction with the pad from the friction of the pads to the rotors. For example the fiberglass is used to handle high temperatures of the pads heating up. Lead sulfide allows the friction to stabilize when dealing with the temperature differences.
Each compound is mixed with each other and weighed to a specific amount. The elements are molded together into a pre fold pad then pressed with a machine. After they press the compounds together they bake them in order for the friction material to form. They test every procedure after they do the steps in making the brakes. The slots in the brake pad allow a bigger source of heat expansion. The organic materials are ran through inspection and then shipped for sailment.
