1. A rotor for an automotive hydraulic brake system which presses a brake pad against a rotating surface mounted to an axle of an automobile, wherein the rotor comprises:

  • a first and a second circular flat plate having an inner circumference and an outer circumference, wherein a plate width is defined therebetween;

    a plurality of supporting fins having a fin length smaller than said plate width and a fin width, wherein said fins connect said first and second circular flat plates in a spaced cylindrical relationship defined by said fin width, and wherein said fins are fixedly attached between said first and second circular flat plates in order to define a plurality of fin channels therebetween said plurality of supporting fins, an inner circumference channel along said inner circumference, and an outer circumference channel along said outer circumference, whereby said plurality of fin channels is interconnected with said inner circumference channel and said outer circumference channel, thereby to define a plurality of continuous pathways between said inner circumference and said outer circumference of said first and second circular flat plates;

    an inner wall approximating said fin width attached along said inner circumference of said first and second circular flat plates;

    an outer wall approximating said fin width attached along said outer circumference of said first and second circular flat plates, wherein said outer wall and said inner wall define an enclosed volume within said first and second circular flat plates;

    a coolant medium;

    coolant injection means mounted on said rotor for injecting said coolant medium under pressure into said enclosed volume, wherein said coolant medium flows around each of said plurality of supporting fins throughout said plurality of continuous pathways, thereby to fill said enclosed volume,mounting means for mounting said rotor to the axle of the automobile, wherein said mounting means is attached to said inner wall along said inner circumference, and wherein said coolant injection means is a valve having an open position and a closed position, wherein said open position permits injection of said coolant medium therethrough and into said enclosed volume, and wherein said closed position seals said coolant medium inserted under pressure into said enclosed volume against removal therefrom.
