2. Brake pad - Wikipedia

   en.wikipedia.org/wiki/Brake_pad

   Brake pads convert the kinetic energy of a vehicle to thermal energy through friction. Two brake pads are contained in the brake with their friction surfaces facing the rotor. [1] When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together onto the spinning rotor to slow and stop the vehicle.

3. Brake lining - Wikipedia

   en.wikipedia.org/wiki/Brake_lining

   The brake lining may also become contaminated by oil or leaked brake fluid. Typical symptoms will be brake chatter, where the pads vibrate as the lining grabs and releases the rotor's surface. The solution is to repair and clean the source of the contamination, replace the damaged pads and possibly also have the rotors re-skimmed or replaced if ...

4. Disc brake - Wikipedia

   en.wikipedia.org/wiki/Disc_brake

   On automobiles, disc brakes are often located within the wheel A drilled motorcycle brake disc. The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. [4]

5. Ceramic matrix composite - Wikipedia

   en.wikipedia.org/wiki/Ceramic_matrix_composite

   An example of CMC manufacture, which was introduced for the production of ceramic brake discs, is the reaction of silicon with a porous preform of C/C. [14] The process temperature is above 1,414 °C (2,577 °F), that is above the melting point of silicon, and the process conditions are controlled such that the carbon fibers of the C/C-preform ...

6. Silicon carbide - Wikipedia

   en.wikipedia.org/wiki/Silicon_carbide

   The Porsche Carrera GT's silicon carbide "carbon-ceramic" disc brake. Silicon-infiltrated carbon-carbon composite is used for high performance "ceramic" brake discs, as they are able to withstand extreme temperatures. The silicon reacts with the graphite in the carbon-carbon composite to become carbon-fiber-reinforced silicon carbide (C/SiC).
