Lightweight brake rotor with a thin, heat resistant ceramic coating

A low temperature light weight brake rotor comprising:

• a braking disc having an inner section integrally formed with an outer section, a braking surface formed about outer faces of each said section;
• a heat reflecting ceramic coating adhered to each of said braking surfaces which acts to insulate and reflect heat away from said braking surfaces, said coating being of a consistent thickness of between 0.015 inch to 0.020 inch;
• and
• a plurality of circumferentially spaced and radially extending cooling apertures arranged between said sections, said apertures act to vent heat away from said disc, whereby;
• during braking a temperature of up to 2000.degree. F. is created between said ceramic coating and a braking pad while the temperature of said rotor is maintained below 260.degree. F.

An aluminum rotor which weighs between three and four pounds comprising:

• a unitary disc member having opposed annular brake shoe engaging faces separated by an interior wall area;
• a plurality of circumferentially spaced radially extending apertures located between an inner surface and a cylindrical outer surface of said rotor, said apertures being of a size so that wall integrity between said opposed faces and each said aperture is between 1/8 inch and 1/4 inch;
• said apertures act as cooling vents which expel heat outwardly from said rotor when in motion;
• a heat reflecting ceramic coating adhered to each of said opposed faces, said ceramic coating being evenly distributed at a thickness of no less than 0.015 inch and no more than 0.020 inch, said coating reflecting heat generated during braking away from said rotor;
• whereby, when said rotor is in the act of braking, heat of up to 2000.degree. F. generated on said ceramic coating is reflected to a sufficient degree so that the temperature of said aluminum rotor is maintained below 260.degree. F.
