Abstract

A fluid cooled vehicle brake includes a fluid flow passage disposed in fluid communication with a brake shoe rim carrying a layer of friction material. A pair of spaced support webs are coupled to an inner surface of an annular inner surface of the rib. A water jacket is sealingly joined to the pair of webs and the inner surface of the rim to form a fluid flow passage between an inlet port formed in one of the support webs along the inner surface of the rim and out through an outlet port formed in one of the support webs. High thermal conductive members may be disposed within the layer of friction material to conduct heat to the rim. Heat radiator members are mounted within the coolant passageway.
