ABSTRACT:
A compressed coolant hydraulic brake rotor is provided for reducing heat energy build-up, thereby minimizing warping and deterioration of the rotor and brake pads. The rotor provides an enclosed volume and a valve assembly used for insertion of a fluid coolant medium, such as freon, within the enclosed volume, which houses a plurality of interior surface support fins. The rotor is "enclosed" in order to contain and govern the fluid coolant medium. As the rotor is engaged and begins to rotate, centrifugal force pressurizes the coolant medium within the enclosed volume and causes the fluid coolant medium to compress. The compressed coolant medium functions as a heat sink to draw heat energy away from the rotor, therefore to cool the rotor by heat energy transfer therefrom. The rotor may be used in any type of vehicle that functions with brakes. Advantages of the present invention include: a reduction of excessive heat build-up on the rotor, thereby extending brake pad and rotor life; and compatibility with all disk brake systems.
