A liquid cooled brake is provided having an improved housing that provides strong yet lightweight structural support. The brake includes end plates disposed about a driven shaft and axially spaced from one another. A plurality of axially extending pins connect the end plates. A friction plate is coupled to the driven shaft for rotation therewith and is axially movable relative to the driven shaft. Another friction plate defines a fluid jacket and is coupled to the pins. The friction plate is fixed against rotation, but axially movable, relative to the pins. A pressure plate is configured for selective movement towards the friction plates. Support columns are disposed radially outwardly of each pin and fixed to the end plates The support columns prevent undue strain on the pins. Ventilated guards may also be located between each pair of columns to limit access to internal working components of the brake.
