Claim:
1. A liquid cooled vehicle brake shoe comprising: an annular rim carrying a layer of a brake friction material on a radially outer surface, the rim having a radially inner surface opposed from the radially outer surface; a first and second spaced rim structural support webs, each extending perpendicularly to and radically inward from the radially inner surface of the rim and joined to the radially inner surface of the rim along an annular edge, the first and second spaced rim structural support webs comprising a mounting surface for a brake shoe on a vehicle; and a water jacket sealingly joined between the first and second spaced rim structural support webs circumferentially beyond the annular extent of an inlet port and an outlet port formed in at least one of the first and second spaced rim structural support webs to form a closed interior defined by the water jacket, the first and second spaced rim structural support webs, and the inner surface of the rim and comprising a fluid flow passage between the inlet port and the outlet port for circulating fluid in heat transfer relationship directly over the radially inner surface of the rim to remove heat from the layer of brake friction material.
