Abstract:
A brake assembly for braking a vehicle comprising:a mounting bracket adapted to be mounted about an axle of a vehicle, the mounting bracket having at least one pin extending outward from the bracket in the direction of the axis of rotation of the axle; a rotor defining a planar surface rotatably mounted to the axle of the vehicle so as to extend in a plane generally perpendicular to the plane of the axis of rotation of the axle; at least one stator defining a planar surface and having passages formed therein to permit fluid flow through the passages, wherein the at least one stator is mounted on the at least one pin of the mounting bracket so as to extend in a plane generally parallel to the plane of the rotor and wherein the at least one stator is slidably movable along the at least one pin in the direction of the axis of the axle so that a planar surface of the at least one stator can engage the planar surface of the rotor; a caliper that has an opening sized to receive the rotor and the at least one stator, wherein the caliper is mounted about the outer perimeter of the rotor and the at least one stator and wherein the caliper can selectively urge the at least one stator to slide along the at least one pin so as to engage with the rotor; and a cooling system for providing cooling fluid to the passages of the at least one stator so that the fluid can remove heat generated by the engagement of the planar surface of the at least one stator and the rotor from the proximity of the rotor.
