Disc brake assembly and dust shield means therefore

A disc brake assembly and dust shield means therefor comprising a caliper assembly cooperating with a pair of friction pads to engage the latter with a rotor to be braked, the caliper assembly being mounted to an axle flange of a vehicle, the rotor being coupled to a hub which rotates on the axle and carries a wheel assembly for the vehicle, characterized in that said dust shield means comprises an inboard plate attached to said axle flange and extending radially outward to but slightly spaced from said wheel assembly and an outboard plate attached to said hub in order to rotate with said rotor, said outboard plate further comprising two parts extending radially outward from said hub to said wheel assembly, the radially outer periphery of said outboard plate engaging said wheel assembly and said inboard plate cooperates with said outboard plate and said wheel assembly to substantially define a cavity for receiving said rotor whereby said rotor and said friction pads are substantially isolated in said cavity from contaminants such as dust and stones on the surface traversed by the vehicle.
