Abstract: A heat shield particularly adapted for use with a wheel surrounded multiple disc brake wherein the wheel is provided with a plurality of circumferentially spaced apart fixed drive keys extending into drivable engagement with a plurality of brake rotor discs. The heat shield is defined by spaced apart wall portions fixedly secured together to form a rigid structure permitting air flow between the wall portions thereof. The heat shield is removably secured in position between adjacent drive keys and in radially spaced apart relationship to the tire supporting rim portion of the wheel to thereby resist heat transfer radially outwardly from the brake to the rim portion and retain heated brake debris discharged radially outwardly by the rotor discs.
